Public bug reported:

Using updated focal, with nvidia proprietary driver, rtl (Hebrew)
interface, all gnome-shell extensions disabled.

When navigating to an open copy of LibreOffice with Alt+Tab, the
application window receives focus, but fails to reflect user input. The
carret is not shown, typed characters are not shown, clicking menus does
not show response, etc. In order to resolve this I have to use Alt+Tab
to navigate away to another app and back to LibreOffice.


To reproduce:
1. Load Firefox, then load LibreOffice Writer and open a document.
2. Use Alt+Tab to move to Firefox.
3. Click several times inside the Firefox window, highlight text, etc.
4. Use Alt+Tab to move back to Writer.
5. Type any character.

Expected result:
- The character is shown on screen.

Actual result:
- More often than not, the character is typed in Writer, but the screen is not 
updated to reflect this. Using Alt+Tab again to navigate to firefox and back to 
Writer resolves this. This makes working with LibreOffice quite difficult.
