Another update, it looks a lot better when running only kwin_x11 --replace with the env var __GL_MaxFramesAllowed=1 - but this hack introduces problems of their own, out of topic for this issue, but still worth mentioning the behavior. Without the env var it also looks extremely smooth if I kill plasmashell, or if I run plasmashell with picom compositing instead of kwin. Suggess not a problem in Kwin or Plasmashell itself, but a specific problem to plasmashell+kwin_x11 (on Nvidia OpenGL drivers). Another thing worth mentioning, this bug https://bugs.kde.org/show_bug.cgi?id=436902 is also kinda mitigated by setting qtquick to Software. Instead of notifications dropping hundreds of frames, it drops a couple which is negligible unless you're gaming and being flooded on Discord :P Can you double check the pager makes a difference. It doesn't make much sense other than more windows are redrawing We have other reports about nvidia resizing being slow that we can work on. Just tested this out and removing the pager applet definitely makes a huge difference for me. *** Bug 460678 has been marked as a duplicate of this bug. *** (In reply to David Edmundson from comment #2) > Can you double check the pager makes a difference.

Just reproduced on a clean Fedora to rule out any Arch oddness or config issue. FWIW it's a 75hz (74,991~) Ultrawide 2560x1080 monitor, GSync disabled when testing, everything on default except I added a couple of virtual desktops so they show up on the widget.
