Created attachment 169777 [details] example of stuttering panels SUMMARY While using Wayland and Adaptive Sync some menus and items are stuttering. Especially some dropdown elements and menus. STEPS TO REPRODUCE 1. Use Wayland and enable adaptive sync 2. Try to open system tray sliding menu and clock menu. OBSERVED RESULT It hangs for a moment and when i hover the mouse over it some time, it goes back to normal EXPECTED RESULT Menus to show up without stuttering. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.0 ADDITIONAL INFORMATION It doesnt occur in X11. Just in wayland and while adaptive sync open. There is a video of it in reddit: https://www.reddit.com/r/kde/comments/1ckq6p9/adaptive_sync_screws_some_animations/ I also attached an example of hanging menu when trying to open it
