Bug ID: 457060
Summary: [Wayland] Cannot adjust second monitor resolution if
application is fullscreen
Product: KScreen
Version: 5.25.3
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: kscreen-bugs-n...@kde.org
Reporter: gerbils...@gerbilsoft.com
Target Milestone: ---
Assume the following display setup:
1. Laptop with 1366x768 LCD
2. TV connected using HDMI at 1280x720
3. mpv running full-screen on the TV
Attempting to set the TV resolution to 1920x1080 results in nothing happening,
though Display Configuration appears to have been successful. Un-fullscreening
mpv and trying this again works without any issues.
STEPS TO REPRODUCE
1. Run mpv fullscreen on the second monitor.
2. Use Display Configuration to change the second monitor's display resolution.
OBSERVED RESULT
Nothing happens, though Display Configuration acts like it was successful.
EXPECTED RESULT
Second monitor should change resolution.
SOFTWARE/OS VERSIONS
Linux: Kernel 5.18.10
KDE Plasma Version: 5.25.3
KDE Frameworks Version: 5.96.0
Qt Version: 5.15.5
Not sure if this is Wayland-specific or if it happens on X11 as well.
