Issue
Occasionally alt-tab hangs the whole system, such that only the pointer can move; it is possible to open tty but not to do anything else. (Possibly Cinnamon would restart, had I bound that to a hotkey, which I have not). The problem occurs only when using coverflow3D - which is the alt-tab mode that I find most useful. Also, it happens on this computer (a ThinkPad X230) and not my other Mint computer (a ThinkPad X1 Carbon Sixth Generation).
Steps to reproduce
Alt-Tab, rapidly and repeatedly. You may need a graphics setup similar to mine.
Expected behaviour
No hang.
Other information
I had thought I had reported this problem before but I cannot find an existing report. I did find some similar reports: 316; 3275; 4388.
The problem has existed for approximate one year, and on different Linux kernels.
