SUMMARY
When I'm using my Wacom Cintiq 16 display pen tablet it is not mapped to the
screen correctly.
In the settings I set it to be mapped to the entire screen, but when using the
pen, it will go outside of the bounds of the screen when the pen goes outside
of the display tablet area.
I was surprised to see the Wacom tablet can actually detect the pen outside of
the bounds of its surface area.
But it seems like there are no measures in place in KDE to restrict that.
Interestingly when using the same tablet and settings on X11, the cursor
position is capped to the bounds of the screen. It will not go outside to the
neighboring screens.
This issue with wayland leads to various issues:
- Window that was worked on can lose focus
- Mouse release event (lifting the pen) will not be registered by the active
window if the cursor leaves the screen
- When using the setting to map the tablet to the active screen, it will easily
swap screens because the cursor can accidentally go out of bounds
OBSERVED RESULT
(See video attachment)
The pen tablet cursor is not capped to the mapped screen dimensions.
EXPECTED RESULT
The pen tablet cursor should be restricted to the screen and dimensions in the
settings (like in X11)
