SUMMARY
The screen seems to freeze during certain animations with Adaptive Sync / VRR
enabled. For instance, when opening the launcher, the screen freezes for a few
seconds until I interact with the menu or other screen update happens, like
taking a screenshot.
STEPS TO REPRODUCE
1. Enable Adaptive Sync (set to always);
2. Open the application launcher.
OBSERVED RESULT
The animation freezes until any screen update happens.
EXPECTED RESULT
The animation finishes in time, without any noticeable increase in frame times.
