Pen offset to mouse

[mathiasyde]

Hello, thank you so much for this guide. I used to draw with Paint Tool SAI full-time until I had enough with Windows and inadvertently stopped drawing - so I'm really glad to see this working! However, the pen is offset to the mouse when drawing (please see image attached.)

I am hoping that you'd have an fix to this, or is able to contact the correct people, because I've tried the instructions in the additional steps in the README of this repository without luck. I've also tried using OpenTabletDriver but, seemingly, SAI does not recognize pen events from this - I can interact with the GUI just fine but it doesn't draw in the canvas.

I am on Pop!_OS 22.04 LTS which has built-in drivers for Wacom tablets. I've only set the runner component in the bottle to caffe-9.2, the others are newer but the guide didn't specify to match with the same versions.

Thank you.

Hello, first off some additional notes from the README, can you try this fix? Avoid maximizing the window any other way.

Putting Sai into fullscreen mode can cause an offset on the mouse. To avoid this:
- Increase the size of the window to fit the screen instead of making it fullscreen
- Fullscreen Sai using F11 to remove the titlebar

Please try these and let me know if it helped solve the issue.

If this doesn't fix it, just as a curiosity, does OpenTabletDriver work on other apps such as PhotoPea? Make sure those two are enabled.

If it works there and there's no offset, we can investigate what the specific issue with PTS2 is when using OpenTabletDriver.

A fix that worked for me: Instead of using caffe as runner, use kron4ek-wine-10.0-amd64, so full screen without F11 everything works.
