Window decoration lost when moving cursor over window bar icons

Post by leejs »

Hello,

I have just upgraded from Mint 17 to 18 and now find that whenever I mouseover any of the decoration in a window, all of the windows lose all of their decoration. I can drag and drop windows, I just can't move the mouse over the 4 dots in the upper left or the expand/minimise/close icons in the top right.

I am able to restore the decoration to all windows by changing any setting in the compizconfig settings manager, but this is obviously very frustrating. Does this mean Compiz is crashing?

How do I go about diagnosing the problem and/or can someone give me a clue as to what's happening here.

Thanks.
