Bug ID: 514859
Summary: Screen blanking after waking up from standby with
Adaptive Sync set to automatic/ always
Classification: Plasma
Product: kwin
Version First 6.5.5
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
When adaptive sync is set to either automatic or always, after the monitor goes
into standby (Power Management > Turn off screen), after waking up, under
certain conditions, it blanks for a second - goes dark, then back. I can
confidently reproduce it with playing a youtube video and exiting / entering
full screen, or taking a screenshot with Spectacle, and sometimes just opening
/ exiting apps such as system settings. The "fix" is to change refresh rate,
e.g. from 240hz to 120, then back to 240.
STEPS TO REPRODUCE
1. Go into System Settings - Power Management; Set Turn off screen to 5 minutes
/ when locked, 2 minutes
1.1. Lock screen automatically: 5 minutes
2. Go to Display & Monitor; Change Adaptive Sync to Always (easiest to
reproduce), or Automatic (most of the time it happens in automatic mode, too)
3. Leave your PC alone, so the monitor turns off and enters standby
4. Wake up the monitor, log in (move mouse for example)
5. Go to youtube and exit / enter full screen, or take a screenshot, or open /
close / maximize apps
OBSERVED RESULT
Screen blanking upon entering / exiting youtube fullscreen
EXPECTED RESULT
Not blanking screen.
