Firefox Screen Freeze in Full Screen mode

[T]

Ubuntu 12.04.

Firefox freezes when I enter full screen mode. By freeze, I *do not* mean that it locks up. I can't think of another word to use. What happens is that anything below the top bar becomes unreadable.

For example, after a period of time in full screen, if I were to go and begin typing a web address, what usually would come down in a drop menu of recent websites doesn't appear. Also, if I am scrolling down a website, it doesn't register. This is the case until I put the mouse at the top of the screen to bring down the top bar, and at this time the new website will register on the screen.

Apologies if this doesn't make enough sense.

This just started happening to me in Ubuntu 15.04 with Firefox 42.0, but only if I run Firefox under the old vtwm window manager:

Firefox 42.0 "Mozilla Firefox for Ubuntu" canonical - 1.0 under Ubuntu 15.04.

The browser now (in the past week or two) locks up when requested to enter Full Screen if not running under any window manager (or when running under an old window manager such as vtwm that doesn't have all the modern hooks).

Reproduce:

1. Start up Ubuntu 15.04 with the full Unity desktop installed.
2. Clean out (remove or rename) $HOME/.mozilla to start clean.
3. Open Firefox.
4. Note that using F11 correctly resizes Firefox to Full Screen and back down.
5. Kill the window manager: run: initctl stop unity7
6. Return to Firefox and try F11 or turn on "Full Screen" from the menu.
7. Browser locks up.

Changing tabs doesn't refresh the screen unless you do something to
trigger an X11 refresh such as opening a menu. F11 does *not* undo the
damage - the browser stays locked up. Using the Firefox menu to disable
(un-check) "Full Screen" also does nothing. Nothing works.

8. Start an old window manager such as "vtwm". No change. Firefox is
still locked up.
9. Exit vtwm.
10. Re-start the Unity window manager: run: initctl start unity7
11. Return to Firefox and use F11 or the menu "Full Screen" a few times and Firefox is working again.
12. Repeat as needed.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu and Firefox since that time.

Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.

Do you still see a problem related to the one that you reported using currently supported versions of Firefox and Ubuntu? Please let us know if you do and in which version of Ubuntu otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
