Since upgrading from 17.10 to 18.04 my video streaming and amimations have become choppy. Running glxgears it can be seen that the animation stops and then starts again every 3 seconds or so. The same with video streaming, the picture stutters every 3 seconds. This happens using the Intel GPU and also using the nVidia GPU via Bumblebee (Optirun).

Does anybody have an idea what could be causing this?

I fixed the problem by removing nvidia-settings and disabling the gnome extension "NVIDIA GPU Stats Tool".

    Why would someone have to uninstall nvidia-settings? – Jonathan May 31 '18 at 20:25

As I understand it, nVidia bumblebee was replaced by nVidia Prime. So try:

sudo apt install nvidia-settings nvidia-prime (and it should uninstall bumblebee) Then restart and open nvidia settings and make sure you pick nVidia card (not intel) and restart again.
