Bug ID: 497749
Summary: touch broken when resolution changed
Classification: Plasma
Product: kwin
Version: 6.2.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: input
Assignee: kwin-bugs-n...@kde.org
Reporter: kdebuac....@porcupinefactory.org
CC: duha.b...@gmail.com
Target Milestone: ---
SUMMARY
The input area doesn't match the display area if letterboxing is used. Touching
a place on the screen doesn't actually register in the touched place, but
offset the farther from the middle it is.
Same with digitizer pen.
STEPS TO REPRODUCE
1. Change resolution from native 1920x1200 to 1920x1080. The display has now a
black bar on the bottom.
2. Touch the Plasma Menu icon on the bottom left
OBSERVED RESULT
Probably nothing happens: actual click is above the button
EXPECTED RESULT
The click should be exactly on the button
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 6.2.4
KDE Frameworks Version: 6.9.0
Qt Version: 6.8.1
ADDITIONAL INFORMATION
Wayland.
This is super annoying because mirroring over multiple screens of different
proportions also has other bugs.
Pen calibration also doesn't fix this problem.
