This issue happened on a laptop of mine with a hybrid GPU setup. It reliably went away after I switched my GPU settings from 'Intel (Power saving mode)' to 'NVIDIA On-Demand'. I am not sure why that is the case. I got the solution within a week or so after I reported this bug. So yes, this issue is not happening any more.
If it will help, I can switch to the 'Intel (Power saving mode)' and test if the issue happens again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1954765 Title: Firefox instance opens with an unusable window that has the content area filled with the frozen image of the window/desktop image in the background To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1954765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
