> Do you use fractional scaling by any chance? Yes, 150% > You can reproduce by resizing any window on an Xorg session? Did some further testing, and I can't reproduce the issue with apps like Chrome or Ptyxis, but I can with Discord, Telegram, and Spotify. Only when they are inside an Xorg session or running under XWayland, if I force them to run as Wayland they are fine.
I turned off fractional scaling, and resizing is fine. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2107245 Title: Resizing XWayland & X11 windows w/NVIDIA is extremely slow Status in mutter package in Ubuntu: New Bug description: When resizing windows that are XWayland (Discord, Spotify, etc) the resize does not take effect until seconds after holding the resize.
