This is also visible in Plasma 6.0.4, in Fedora 40. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 OS: Fedora KDE 40 I can confirm that issue on Nobara (AMD GPU) and Manjaro (Intel/Nvidia), both Plasma 6.0.4. It sometimes freezes for a longer period, until you move the cursor or the screen refreshes. So it seems to be a timing / refresh issue. I missed this bug when I created https://bugs.kde.org/show_bug.cgi?id=493940 For me these look like duplicates, could you check if you agree? I have some recordings of the bug added. Zamundaaa swept in an quickly fixed it, therefore maybe this is also resolved? *** This bug has been marked as a duplicate of bug 493940 *** |
Created attachment 167093 [details] Output from glxinfo 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. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 OS: NixOS 24.05 (Wakari) ADDITIONAL INFORMATION Output from glxinfo attached.
