Hey! I just upgraded to 20.04 from 19.10, and had the same issue (same GPU - Intel Graphics UHD 620). I had the same problem a few months ago using the OIBAF ppa, and I thought it was because of the Open Source driver (built twice a day from their git repo) and since removing the PPA fixed the issue. I stepped upon this bug report when searching for a reason to my screen artifacts (same problems, same symptoms and same image as the original post). I've read the last comment "Please don't use the 'intel' driver. It is old and unsupported." and remembered that I had screen tearing issues a few months ago and that I added a custom XORG config (following https://askubuntu.com/questions/1066722/intel-screen-tearing-ubuntu-18-04). I just emptied '/etc/X11/xorg.conf.d/20-intel.conf', and rebooted, and it just worked fine from this! Please check if it could fix it for you too!
