Short description of error

Set the tablet api to Wintab
Start creasing some edges and repeatedly lift and return the pen to the tablet area

This is apparently the same bug from this task https://developer.blender.org/T84855
It was solved for 2.93 but the problem returned.

Hi @PrototypeNM1 , are you able to reproduce?
Was this issue fixed in 60c0b79256?

@PratikPB2123 This is a driver specific issue (not locally reproducible). I don't generally close these until I can verify the issue isn't "the driver's behavior is weird but not invalid".

This wasn't fixed by the fallback. The fallback heuristic compares Wintab button presses to Win32 button presses to see if the two agree. In this case the issue is the cursor moving when the pen leaves, so there isn't a similar "sync point" to check.

Same thing happens with my Huion Kamvas 22plus. I’ll try to see if there is a driver update, but I think it already is updated. And it worked fine with Blender 2.93.

@PrototypeNM1: So is there anything the #triaging team can do here?

@lichtwerk nothing for #triaging to do at the moment.

The problem still exists ( Blender 3.1). The keyboard does not work when lifting pen from tablet area ( wintab ). With windows ink there is no such problem, but there is another problem with shift,ctrl,alt pop up, that microsoft does not want to fix. My tablet is huion kamvas 13.

@Lillya @sakuramurai Can you run the current nightly from command line with the argument blender.exe --debug-wintab, recreate the bug, and copy the command line output here, and link the resulting paste to this report?

@Lillya I don't think this build will fix the issue, but could you try it with the same instructions as before? I noticed something invalid in the logs that should be fixed now. Heads up that if pressure doesn't work it's because it turns off in the case of some failures in this build.

@Lillya I don't think [this build](https://builder.blender.org/download/experimental/blender-3.3.0-alpha+wintab.6abc638a8b90-windows.amd64-release.zip) will fix the issue, but could you try it with the same instructions as before?

Could you try this build, and if things are still broken then same instructions as before for getting the log.

Note for self: this build tests if using PK_CHANGED filters invalid data.
