Bug ID: 490415
Summary: Color corruption after resume from sleep
Classification: Plasma
Product: kwin
Version: master
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: colour-management
Assignee: kwin-bugs-n...@kde.org
Reporter: jhanm...@ca.rr.com
Target Milestone: ---
SUMMARY
Problem only occurs with kwin build > v6.1.2. All other Plasma 6 components are
newly built using kde-builder. Switching KWIN back to v6.1.2 appears to correct
the screen/color corruption issue. Failing system is a Radxa Rock-5b (Rockchip
RK3588 SoC) running Armbian Ubuntu 24.04 with all updates. Qt 6.7.1 is also
installed.
STEPS TO REPRODUCE
1. Put system to sleep.
2. Press power button to wake system from sleep.
3. Screen has what appears to be corrupted color mapping, i.e., image is
visible but hard to read because colors are wrong.
OBSERVED RESULT
What appear to be corrupted colors are on the text consoles (Alt-Shift-F3,
etc.) and the KDE Plasma graphical screen (Alt-Shift-F1). This appeared to
happen in KWIN versions prior to 6.1.2 on my system also but switching to the
text consoles and then switching back to the graphical screen corrected the
screen corruption. With versions after KWIN v6.1.2 it doesn't appear possible
to correct the screen/color corruption without a reboot.
EXPECTED RESULT
System should resume correctly.
