                    bar causes lag

           Version: 6.0.1
          Platform: Arch Linux
                OS: Linux

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.
