Comment 14 for bug 1306550

Also have this bug, took me a while to find this bug description here (searched for "mouse focus off" previously), which is probably the reason why it seems that it does not affect that many people.

As mentioned in the similar bug https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1309290 I can (almost) always recreate the bug if I minimize a window and click on the launcher icon again. Then the focus and mouse pointer are off as described by others (interestingly also "somewhere below and to the right").

Happens with Firefox, Chromium, Thunderbird, file explorer, ...

Workaround: as I usually see no menu bar - grab the window (to un-maximize it) and throw it to the top again to maximize again. Then the behaviour is back to normal in this very window.

If I have one Hot Corner activated (right bottom edge for "show desktop") and the mentioned "Show live previews of windows" in Compiz Manager deactivated (otherwise the hot corner does not work), bug occurs. If I deactive this hot corner (none else activated) and check the show-live-previews (to activate it), the bug seems to be gone (although, with this option checked hot corners do not seem to work on my system...)

Should not be an Nvidia problem as I have AMD and an on-board Radeon GPU.

I have the strong feeling that this bug is related to graphic-driver issues, although it seems to occur in different systems.... has anybody tried other drivers than the ones that come installed with the system?
