Summary: [wayland] Adaptive Sync option sometimes disappears
when waking from sleep
Classification: Applications
Product: systemsettings
Version: 6.1.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_kscreen

Target Milestone: ---
SUMMARY
Occasionally when walking my laptop from sleep, the "Adaptive Sync" option will
disappear from the System Settings' Display Configuration menu.
I have not noticed this happen on Plasma 6.0.5 or below with the brief period I
used it on this laptop, or on my PC which has been running Plasma for a long
time and which I wake from sleep quite regularly. I have not yet seen the
Adaptive Sync options disappear on Plasma 6.1.0 on my PC, but it is happening
on my laptop.
I am not sure if this means Adaptive Sync is disabled or not. But I have
noticed that when the setting disappears, my battery life significantly tanks
(the display is 165hz).
if there is a way that I could check the status of Adaptive Sync from the
commandline please let me know, I would be interested to check if it is
actually being disabled when the setting disappears!
STEPS TO REPRODUCE
1. Put a device to sleep and wake it up.
2. Occasionally the Adaptive Sync option will disappear and won't come back
until a reboot.
OBSERVED RESULT
Adaptive Sync option occasionally disappears when waking device from sleep.
EXPECTED RESULT
Adaptive Sync option should not disappear when waking from sleep.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 6.9.5 Linux Zen
KDE Plasma Version: 6.1.0
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.1
ADDITIONAL INFORMATION
Perhaps this is a driver issue when waking a laptop from sleep that is
reporting to KDE that Adaptive Sync is unavailable?
