Description cromachina 2025-06-16 15:10:12 UTC 
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.

Quote from gonX:
> FWIW, Sway does not seem to exhibit any of these issues in Artist Mode, but I do also understand that Sway isn't exactly a drop-in replacement for neither Gnome nor KDE.
Which possibly indicates the issue is with the input handling of kwayland.

This is intentional. Pointer and tablet input are independent.

That is terrible. Wayland not for artist with use graphic stylus pen user?
this intentional for really security and usability?
Krita or gimp or many create tool no usability with use graphic stylus and mouse in wayland.

If I krita drawing, if I little touch mouse, cursor position warp, So dive in panic.
I can't draw with this non usability wayland. Why I using X11 answer is this.
