Thanks for following up! If you don't mind switching back to 'Intel (Power saving mode)' and testing again, that would be helpful. When you do that, can you please test an upstream build (downloaded from https://www.mozilla.org/en-US/firefox/download/thanks/) to see whether it's an Ubuntu-specific problem?
Otherwise, feel free to close the bug. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in 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 Status in firefox package in Ubuntu: Confirmed Bug description: After a recent Firefox update (I think this started after the Firefox 95 upgrade), opening Firefox often opens a window with a visible title bar that indicates that the application in focus is Firefox but the content area is invisible because it has the frozen image/background of either the windows/application behind the Firefox window or the desktop background image if there are no windows behind Firefox. The Firefox shortcut keys work and I am able to open a site by pressing Ctrl+L to focus the address bar and type a domain name/URL. The website/URL loads okay but nothing is visible because of the content area being hidden by the frozen image. Resizing/minimizing+maximizing the Firefox window doesn't resolve this issue. However, when I launch Firefox from the terminal, it works properly every single time. So it looks like there might be some issue only when launching from the Firefox application launcher (.desktop file).
