Bug ID: 505663
Summary: Tablet pen and mouse do not sync cursor positions when
using Wayland
Classification: Plasma
Product: kwin
Version First 6.3.5
Reported In:
Platform: NixOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
When using the tablet pen, it takes over the cursor position, but when using
the mouse again, the cursor position teleports back to where the mouse cursor
was last at. It does not do this with X11. This is kind of annoying and it
would be nice to have an option to have cursor positions be synced like in X11.
STEPS TO REPRODUCE
1. Move your mouse around, like on a different monitor.
2. Use your tablet pen to move the cursor (in absolute position mode, or
"artist mode").
3. Move the mouse around again.
OBSERVED RESULT
The cursor teleports to the last mouse position.
EXPECTED RESULT
The cursor continues moving from where the tablet left the cursor last.

Which possibly indicates the issue is with the input handling of kwayland.
