Public bug reported:
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).
