Reproduce ========== I can't reproduce it on demand. But it happens after a while. - Usually I browse within a Firefox incognito window and use my middle mouse button. - In todays particular case, I pressed the middle mouse button to close a window. - Note: I have `EasyStroke` setup to run on middle-mouse-button click (Program to enable mouse gestures). From experience, I strongly believe this is related. - Maybe `suspend`ing the computer several times is related to this problem. Backtrace ========== Reading symbols from /usr/lib/xorg/Xorg...
