fix(gamescope): direct-touch drags work again in games that confine a hidden cursor - #2220
In Direct touch, dragging stopped working in games that draw their own cursor (Balatro, Stardew Valley). A drag moves the pointer but never holds a button down; taps still click.
Since #2053, patch 0128 makes gamescope switch to relative mouse for any game that hides the cursor and confines the pointer, not only for games that lock it. Those cursor games confine the pointer to their window, so gamescope took the host pointer lock. DroidDeck then treats every direct-touch swipe as camera motion.
Repro on a RedMagic Astra 2: a guest X11 window with a blank cursor that confines the pointer to itself. A tap gives press and release. A swipe gives 94 MotionNotify events with state 0x0 and no ButtonPress.
Fix
New gamescope patch 0133-confined-pointer-relative-when-held:
Goes relative: a confine (not a lock) switches to relative mouse only while the game actually holds the X pointer, i.e. stays more than 48 px from gamescope's pointer on 3 moving frames within 500 ms, as games that recentre or clip the pointer do.
Goes back: after 60 moving frames where the pointer follows again, when the confine ends, or when the cursor shows.
Unchanged: locks, the 0131 follow rule, forced relative mode and the per-game Off switch.
The app needs no change: its "a pointer lock means camera" rule is right again once gamescope only locks for real holds.
Tests
test_gamescope_confined_pointer_hold.py compiles the rule straight from the patch and checks that:
a confined pointer that follows never goes relative;
a held pointer goes relative after 3 frames and is released when it follows again or the confine ends;
locks are unaffected.
All gamescope patch tests and the direct-touch app tests pass.
Device checks with the CI-built gamescope to follow on this PR.
No actionable comments were generated in the recent review.
Summary
Summary by CodeRabbit
Bug Fixes
Relative mouse mode now better reflects whether a game holds the pointer. Hinted constraints start in relative mode; other constraints enter it when the pointer follows less than a quarter of sent movement on three frames within half a second. Hinted constraints leave relative mode after 30 frames of pointer movement following sent motion.
Pointer-locked touch movement no longer prematurely marks a pending direct-touch hold as used.
Tests
Added coverage for pointer-hold detection, movement, timing, and constraint release.
Documentation
Updated patch notes to describe the behavior and its tests.
Patch 0133 adds Gamescope pointer-hold tracking and uses the held state to select relative-mouse mode. It adds tests and patch notes. The pointer-locked touch path also changes when it cancels a pending direct-touch hold.
Tracks constrained-pointer movement against cursor movement and accumulated sent-motion deltas. Three qualifying frames within 500 ms mark the pointer held; 30 non-away frames release it. Tracking resets when the cursor or constraint is unavailable or the focused window or constraint changes.
Apply hold state to relative mode tools/gamescope/patches/0133-constraint-relative-when-held.patch, tools/gamescope/PATCHES.md
Updates tracking on eligible vblank frames and uses the held state in the constrained-pointer relative-mode condition. Keeps the forced-relative, follow-client, and override rules. Documents the tracking rules and their relation to patch 0128.
Test hold behavior and mode selection tools/tests/test_gamescope_pointer_hold.py
Adds a compiler-gated C++ harness and source assertions for hold transitions, sent-motion accounting, reset behavior, and relative-mode conditions.

Summary
Change direct-touch hold cancellation app/src/main/java/com/droiddeck/launcher/SessionActivity.kt
The pointer-locked move path cancels only the pending hold when a locked swipe was already used. Otherwise, it cancels the hold outright.
Droid-Deck/DroidDeck#845: Reports camera control stopping at the screen edge with cursor confinement and warping. This change alters relative-mode selection on the constrained-pointer path, but does not address the reported case with no camera movement.
Droid-Deck/DroidDeck#916: Reports mouse-aim and unwanted camera-turning symptoms. This change alters the related constrained-pointer relative-mode path, although the issue does not confirm the cause.
Moving a locked pointer after a direct-touch long press can release right-click before the movement. Fix this interaction before merging unless that regression is explicitly accepted.

Explanation
[#2199] Requirement: touch-drag must work in games such as Balatro. The issue sets no further acceptance criteria. At head, the patch file tools/gamescope/patches/0133-constraint-relative-when-held.patch exists (confirmed by file listing). Per the change summary, the relative-mouse gate in src/steamcompmgr.cpp now uses bGameHoldsPointer = bHasPointerConstraint && s_bPointerHeld, replacing the prior any-constraint check. A pointer counts as held when the X pointer misses seat motion by more than 75% (seat motion at least 4 px) on 3 frames within 500 ms. A following pointer stays absolute, so direct-touch button state is kept. Held state clears after 30 free frames or when the focus window or constraint changes. A hinted constraint starts held. The later commits add a focus or constraint reset (316355a) and a SessionActivity.kt forwardTouch ordering fix (343acf1) for a lock that starts mid-swipe. Gaps: I read the change summary, not the patch or test source, so the patch logic rests on that summary. The regression test tools/tests/test_gamescope_pointer_hold.py is reported present but was not read or run. On-device Balatro behavior is not verified; device checks are manual and not coding requirements. The PR description is stale: it names 0133-confined-pointer-relative-when-held and test_gamescope_confined_pointer_hold.py, and describes a 48 px threshold and confine-only gating, none of which match head.

Explanation
[#2199] Changes at head stay on the direct-touch drag path: patch 0133 (PointerHold, pointer_hold_step, update_pointer_hold, and the relative-mode gate in steamcompmgr.cpp); flSentDX/flSentDY accumulation in wlserver.cpp and wlserver.hpp, used only by the hold logic; the SessionActivity.kt forwardTouch ordering change; the regression test; and tools/gamescope/PATCHES.md notes. The gate keeps the forced-relative, s_bFollowClientPointer, and nRelativeMouse == 2 terms. Behavior difference from the PR description: the gate no longer separates confines from locks. Unhinted locks switch to relative mouse only after hold detection, about 3 moving frames. Hinted locks start relative. The PR description says locks are unchanged, which is not accurate. This difference comes from the same fix, so it is related and not unrelated. The PR description should state this behavior and name the files present at head.

Patch 0128 made every hidden-cursor confine relative. Games that hide the
system cursor, draw their own and confine the pointer to their window then
took the host lock, and a direct touch drag became camera motion with no
button held, so cards and items could not be dragged.
A confine now goes relative once the X pointer stays away from the seat
position while input moves, as when a game recentres it or clips it to a
small rectangle, and returns to absolute when the pointer follows again or
the confine ends. Locks and the warp follow rule are unchanged.
…e holds the X pointer
Xwayland turns a hidden-cursor grab into a lock with no cursor position hint, so the confine-only rule never applied to games that draw their own cursor (Stardew Valley, Balatro). A hinted constraint is relative at once, as upstream. An unhinted lock or confine goes relative once the X pointer stops following the seat's motion, which a recentring or clipping game does and a drawn-cursor game does not.
Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Away count survives intervening free frames, so the hold can trigger on sparse noise.
Free frames do not reset nAwayFrames. Only a gap over 500 ms between away frames resets it. When bHeld is false, a "free" frame takes no branch, so the counter stays unchanged.
A game can follow the seat for most frames and still have three isolated away frames inside any 500 ms window. For example, a brief pointer clip at a screen edge can cause these. Then bHeld becomes true. The game gets relative mode, and direct-touch drags turn into camera motion again. This is the regression the patch aims to fix.
The documentation says "three frames within half a second". It does not say "any three frames, even if separated by free frames".
Decide if this is intended. If not, reset nAwayFrames on free frames while bHeld is false.
Proposed fix
- else if ( state.bHeld && ++state.nFreeFrames >= 60 )- {- state = PointerHold{};- }+ else if ( state.bHeld )+ {+ if ( ++state.nFreeFrames >= 60 )+ state = PointerHold{};+ }+ else+ {+ state.nAwayFrames = 0;+ }
If you want to keep the current behavior, confirm that "consecutive" is not required. Then update tools/gamescope/PATCHES.md to match the code.

… the X pointer
Stardew Valley's grab with a hidden cursor becomes an Xwayland lock with a cursor position hint, which upstream made relative at once. Without relative mode that lock still follows gamescope's relative motion and touches still place the pointer, so the hold rule now decides for every constraint, hinted or not.
…ointer follows
Releasing a hinted lock only through the hold rule let a recentring game's first touch swipe press the button. A hinted lock now starts relative as upstream and is released after 30 moving frames on which the X pointer follows the motion gamescope sends, counted from the relative motion while the seat is locked.

Clear the hold when tracking is disabled outside vblank.
If the cursor shows and hides between vblanks, the selector can reuse the previous hold. Off mode has the same problem if it is turned off and back on between vblanks. A following pointer can then enter relative mode, causing touch drags to act as camera motion until the hold clears.

…swipe
A game that only shows its pointer lock after its first warp took the first
swipe as an absolute drag, with the button held until the finger lifted.
The first locked move now ends the forwarded touch before sending deltas.

Preserve an active right-button hold during locked movement.
With direct hold set to MOUSE_BEHAVIOR_HOLD, a long press sends right-button down. The first locked move now calls cancel(), which releases that button before sending the delta. Users can no longer hold right-click while moving the locked pointer. Previously, cancelPendingHold() preserved the hold until finger-up. (raw.githubusercontent.com)

Problem
In Direct touch, dragging stopped working in games that draw their own cursor (Balatro, Stardew Valley). A drag moves the pointer but never holds a button down; taps still click.
Since #2053, patch 0128 makes gamescope switch to relative mouse for any game that hides the cursor and confines the pointer, not only for games that lock it. Those cursor games confine the pointer to their window, so gamescope took the host pointer lock. DroidDeck then treats every direct-touch swipe as camera motion.
Repro on a RedMagic Astra 2: a guest X11 window with a blank cursor that confines the pointer to itself. A tap gives press and release. A swipe gives 94 MotionNotify events with
state 0x0and no ButtonPress.Fix
