Desktop animations show quite inconsistent performance, in the form of jitter. Sometimes animations are butter-smooth, others they are completely choppy.

I have tried isolating the cause, but I was unable to. The only differences I could tell are these:

- If you install optimus-manager and nvidia-open, and use X11, animations are always smooth. On both the internal and external screen. Still they are inconsistent on Wayland.

- If you run OBS on Wayland, with the display as source, animations will always show jitter.

Things I have tried without perceiving a clear difference:

- Using the modesetting driver, or nvidia-open, or nvidia proprietary.
- In "/etc/profile.d/optimus.sh" doing "export __NV_PRIME_RENDER_OFFLOAD=1" and "export __GLX_VENDOR_LIBRARY_NAME="nvidia". Or the opposite "export __EGL_VENDOR_LIBRARY_FILENAMES="/usr/share/glvnd/egl_vendor.d/50_mesa.json"".
- Using an external monitor, or only the internal one.
- Setting multiple Kwin Environment Variables.
