Created attachment 166814 [details] Showing the lag in switching desktops when the app is dragged in different positions Switching virtual desktops with apps touching panel bar causes performance issue STEPS TO REPRODUCE 1. Make sure that multiple virtual desktops are enabled 2. Open any application in any virtual desktop 3. Either make the app fullscreen OR drag the app close enough to the panel bar so that the bar switches to non-floating mode 4. Switch to and from another virtual desktop using either hotkeys or the pager widget OBSERVED RESULT Kwin struggles to move smoothly between desktops, so the animation is laggy and slower. EXPECTED RESULT The switching animation should be fluid and take a consistent amount of time. SOFTWARE/OS VERSIONS Linux kernel: 6.7.9-arch1-1 (64-bit) KDE Plasma Version: 6.0.1 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 ADDITIONAL INFORMATION I am using the proprietary Nvidia drivers because of compatibility with a video editing program. Unfortunately I don't remember if the issue occurred with Nouveau before I installed the proprietary drivers.
Hi - I'm not able to duplicate this on Neon (Plasma 6.0.2) and Intel graphics. I suspect this is NVIDIA related. Could you please verify if this is still happening on 6.0.2? We may need someone with NVIDIA graphics to confirm this one.
Are you on X11? If so it seems like this may be Bug 482717.

(In reply to Nate Graham from comment #2) > Are you on X11? If so it seems like this may be Bug 482717. I am on Wayland. The issue looks similar to 482717, but this one only occurs due to the windows proximity to a panel bar. Combining these two facts, I suspect that the problems are different, though it is still possible.
