Just got a new Lenovo Thinkpad and using Ubuntu 20.04, and I think I'm seeing a very similar issue. After leaving the laptop on for so long eventually a ton of the text menues and displays either show NO text at all, or half of the characters are missing. I'll attempt a screenshot the next time it happens, it doesn't take longer than a day it seems as already reported.
I also use Discord so I wonder if that is part of the culprit as well. Will try using without Discord for about a day. I have found a simple logout/login is enough to fix all text menues. So it doesn't seem a full reboot is strictly necessary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910938 Title: Text is missing from shell panel and menus To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1910938/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
