AGC: PPSA01748 stops at start-up since #9789 (color export format 4 into an unsigned integer target is unsupported) #12639

What happens

Marvel's Guardians of the Galaxy aborts about 5 minutes after launch, before its first menu, with AGC graphics: color export format 4 into an unsigned integer target is unsupported. Before #9789 the same title reached its main menu.

System

Linux 7.3 (CachyOS), NVIDIA GeForce RTX 4090, NVIDIA 615.78.08, GCC 16.2.1, Release.

Steps to reproduce

Relinked with --to-intel, then launched with no input until it stops. Switches set: APS5_PROFILE_DRAW=1 APS5_TRACE_RESOURCE_KEY_MISSES=1 APS5_TRACE_DISPATCH_CACHE=1 APS5_TRACE_FRAMES=1150:40 APS5_NO_PAD_INPUT=1 (diagnostics for another report; the check that throws is in the state decode and does not read them). It stops 308 s after launch.

What was checked

• Control: the same build with only b15a58d (fix(libSceAgcDriver): export raw 32-bit values into UINT color targets as integers #9789) reverted, same switches and caches, gets past that point and reaches the main menu; it was closed from the menu after 864 s with exit code 0. One run each.
• Before fix(libSceAgcDriver): export raw 32-bit values into UINT color targets as integers #9789: e13027a with fix(agc): require full coverage only for metadata pass targets with CMASK or DCC keys #9694 and perf(agc): prebuild registration libraries on half the hardware threads by default #10388 (both merged since) reached the main menu in every run on 2026-10-23 to 10-28.
• The throw is the new check in State.cpp (DecodeState): a pixel shader whose export for a UINT target is not 32_R, 32_GR, 32_AR or 32_ABGR. Format 4 is FP16_ABGR. Before fix(libSceAgcDriver): export raw 32-bit values into UINT color targets as integers #9789 this combination reached Vulkan, and the title rendered its menus.
• I don't know what the console's color block writes for an FP16_ABGR export into a UINT target, so I have not tried a fix. @rooklz, is the throw meant for this combination, or should FP16_ABGR keep the earlier path?
