Bug ID: 502087
Summary: Turning HDR on on 165hz 2k monitor makes system
unresponsive and lower makes the monitor unsersponsive
Classification: Applications
Product: systemsettings
Version: 6.3.3
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: thankare...@gmail.com
Target Milestone: ---
SUMMARY
When I try to enable HDR on odyssey g5 32 inch 2k monitor connected by display
port if the refresh rate is set to 165hz, the desktop freezes fully and there
is no way to recover other than turn it off forcefully. When I log in again
every screen is black, and I need to forcefully shut down again go to the tty
and delete the .config/kwinoutputconfig.json only then I can log in again
without everything freezing, or I need to unplug the monitor but if I plug it
again and the HDR was on it will freeze again. I use a lot of monitors, but it
still happens with the two monitors. If I reduce the refresh rate to 144hz or
lower I still can't enable HDR but the pc doesn't freeze but the HDR monitor
stays black (other monitors work in this case and I don't need to forcefully
shut down and remove the file to remove HDR). HDR works fine on Windows on same
machine on same refresh rate. I am using a 5070 with 570.133.07 open drivers.
STEPS TO REPRODUCE
1. Set refresh rate to 165hz (or lower for similar problem)
2. enable HDR
OBSERVED RESULT
Everything freezes (all the monitors) or the HDR enabled monitor is not working
EXPECTED RESULT
Not freeze or the HDR monitor to turn on
