The bug is fixed when I updated mutter to 3.36.1-1ubuntu0.20.04.1. BUT!!!!
After an "Automatic Screen Lock", the display turned off, the Gnome Shell crash and show us a blank screen with the message "Oh no! Something has gone wrong." This bug did not appears before the update. I have a NVIDIA card. I think that this problem occurs only with NVIDIA users. I have other PC (without a NVIDIA card) and the problem not occurs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892440 Title: Shell text with wrong size in mutter 3.36.4-0ubuntu0.20.04.2 (mostly on Nvidia) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1892440/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
