I have an issue with Gnome and Ubuntu 20. In particular, top bar text and drop-down menus characters randomly disappear, in a similar way to this. The only fix I found is to reboot. Does anyone have any idea on how to fix this?

P.S. My software is up to date.

EDIT: Info about my computer and graphics card:

    not an solution, but perhaps an better solution than rebooting: press Alt+F2then type r and confirm with enter -- this restarts Gnome-Shell

  • @vanadium Are there any preinstalled extensions I should be aware of? I haven't installed any.

Had the same issue. Reboot did not fix. db429's suggestion of restarting Gnome-Shell worked, though not instantly. I noticed everything (header, desktop icon text) back after a few minutes, but as noted in comments it was just a long few seconds.

Steps: Alt+F2, type r, hit enter, even if you can't see what it says when you do so.

  • db429's solution works for me too. Everything is back to normal in a few seconds on my machine.

  • Happened again and checked - back in 7 seconds. Long enough that I missed it changing after. Thanks again all.

  • In 20.04, alt+F2+r works, but after upgrade to 22.04, this does not work. Still try to find other solution

  • I'm 90% sure I've used it successfully on 22.04, but it's also been happening a lot less in it.
