Does anyone know why is that and how I can get rid of them?

In case: my video cards are

I'm still looking and I seem to have found a solution ... see this thread. Fuzzy graphics after upgrading to Ubuntu 20.04 when using the code

sudo apt purge xserver-xorg-video-intel

At least it worked for me and I no longer have broken graphics on my multi-PGU machine.

I join the interviewer and follow this thread. I have the same problem. I have a machine with a multi-GPU = integrated Intel HD Graphics 630, a dedicated 7x NVIDIA GeForce GTX 980 Ti. Since I only use nVidia for CUDA calculations, the display is sent to Intel HD - by editing /etc/X11/xorg.conf
