Bug ID: 491956
Summary: Touchscreen does not resize when window resizes
Classification: Plasma
Product: kwin
Version: 6.1.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: libinput
Assignee: kwin-bugs-n...@kde.org
Reporter: tdaw...@redhat.com
Target Milestone: ---
SUMMARY
When you change the resolution of your screen, the touchscreen does not change
with it. This causes you touches to be places you are not expecting.
Note: This does not happen when you re-scale your display, only when you
change the resolution.
STEPS TO REPRODUCE
1. Start with a normal Plasma 6 install on a machine with a touchscreen.
2. Change the resolution. Possibly most important, change the aspect ratio
(16:9) -> (5:4)
3. Try touching things, especially things not in the center of the screen. I
have found that using the onscreen keyboard is the easiest way to see this,
because it highlights the keys that are pushed. But it is not related to the
keyboard.
OBSERVED RESULT
Depending on how dramatic the resolution change, and how far off center (both
horizontal and vertical) I am touching, where I am touching, and where my
desktop thinks I'm touching can be wayyy off.
EXPECTED RESULT
The desktop should think I am touching where I am touching.
