Bug ID: 54492
           Summary: Clip Studio Paint - Modifier Keys break stylus input
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

When drawing in Clip Studio paint, hitting modifier keys like Ctrl Shift Alt
etc will cause the cursor to glitch and start rapidly flashing between
different input methods.

Can only be fixed by restarting the program, but holding down a different
modifier key pauses the glitching.

This occured on multiple Arch based systems (Manjaro and SteamOS) with an
Artist 15.6.

I have tested this with both the built in libwacom (I think) drivers, and
XP-Pen's own drivers, no change in the behaviour.

The behaviour does NOT occur with a mouse. It is only with a stylus.
