Comment 36 for bug 1181666

I have the same or very similar problem on Ubuntu 16.10.

It happens usually after certain programs are run (like notepadqq, sometimes open office or image viewer and most usually Netbeans, with Netbeans on it's nearly certain it will happen on my laptop after some time running, especially when there are more programs). It usually blocks Chrome from navigating tabs, sometimes other windows from clicks or resizing. If not with Netbeans then usually when doing something processor and ram intensive in background (but not as much intensive to be low on memory, like having 16 GB RAM and using 6 GB and 100% of 2 processors).

Strangefully usually closing Netbeans help for me - but not always. Sometimes it's ok after closing but problem is back in few minutes after closing.

It looks like it might be related to some resource in the system but I can't guess which one.
