--- Comment #5 from [e-mail] ---
I am an affected user who investigated this issue further.

Thanks to the very detailed technical analysis provided by @Maxime Nordier in
Comment 2, the root cause was clearly identified as a missing pressure(0) event
in the Smithay Wayland compositor library (used by Niri and others).

Following this analysis, I submitted a compatibility patch to Smithay. The fix
has now been successfully merged into Smithay's master branch.

Merged PR: https://github.com/Smithay/smithay/pull/1851

This change aligns Smithay's tablet event behavior with major compositors like
Sway and GNOME, and is expected to resolve the continuous drawing issue in
applications like Clip Studio Paint under Wine.

Thank you very much, @Maxime Nordier, for your excellent investigation and
information.
This bug should be resolved for users once affected compositors update their
dependencies to the latest Smithay version.
