Comment 5 for bug 1356892

I can confirm this happens on Ubuntu Mate 14.04.2 32 bit with Compiz enabled. I am using an ASUS board and intel i3 quad core and an AMD Radeon R7 200 GPU. I am using Ambiant Mate theme with Faenza Dark icon set. But, I can also confirm this happens irrespective of theme used.

This problem seems to occur irrespective of whether a window is in focus or not. Or, at least, once I have noticed it, it doesn't matter if the window is the active one or not. The minimize, maximize and close buttons are gone and stay gone. That is to say, they are not merely greyed out. They have disappeared. The only fix I have found for it is to go to mate tweak, change from Compiz to Marco, then immediately back to Compiz and the buttons re-appear.

However, the problem reoccurs within around 15 to 20 minute on average.
