[Bug 753144] [NEW] focused, or maximized windows blank


Public bug reported:

Binary package hint: compiz

I have discovered a fairly consistent behavior: When multiple
aplications are open, the bug can manifest itself as: the active window
is blank (white in my case... title bar displays but nothing else.)
while windows behind it will display content. If one of the unfocused
windows is selected, it gains focus, and goes blank. The previously
blank window, no longer focused, regains its content and is no longer

Switching between applications, the ones gaining focus always going
blank only to regain content after losing focus is quite infuriating.

To force an application to quit being blank, another application is
opened, and applications are switched until the blanking behavior begins
for the new application. (I use terminal as my dummy app...) Terminal is
given focus, observed to be blank, and closed. The aplication which was
behind the dummy application gains focus, and does not go blank. (this
has been verified in classic desktop, not yet in unity)
