--- Comment #11 from angn...@gmail.com --- I reproduce the bug with a non-maximized but full-sized window, on the primary and secondary monitors, with and without toolbars. To reproduce on my 2560x1440 monitors (Nvidia driver): 1- resize the firefox window+decorations to the monitor resolution (2560x1440 in my case, adjust to yours). The window can be anywhere, only the size is important. 2- press F11 Expected: Full Screen window Actual: Black screen Also tested and reproduced with VLC, same procedure.
