AMD A6 5400k white screen on fullscreen

I ve moved a patch to a new computer (from i7 gtx to APU A6 5400K) and when the patch goes fullscreen I get a white screen.
This not a consistent behavior as it does not happens with other patches and it seems to disappear if you juggle a bit around… (what a nice issue report…)
Anyway to be more specific, has anybody had similar problems with AMD APUs?
