I am Ubuntu 18.04 lts Budgie, and somehow whenever I am not moving my mouse, either on fullscreen or not, the video freezes, until I move my mouse again. It happens all the time, on Chrome and Chromium.
I do have Nvidia proprietary driver installed.
Someone asked something similar but for Ubuntu 11, and It's a bit outdated.
Edit: it doesn't happen on Firefox from what I have seen so far.
Thanks in advance :)
