Same problem occurs for me with nvidia-driver-470. The graphical effect / issue is a bit different, yet. See attached pic... My Ubuntu 20.04 is as up-to-date as possible.
The last suggested solution is working for me (restarting gnome-shell), but this is still annoying... I've just read this : https://www.reddit.com/r/gnome/comments/k5ea3g/text_and_icon_glitching_out_after_resuming_from/ so it seems we won't have any solution before quite a long time... Fed up with nvidia !
