Almost 6-7 times per day. I believe this is related to desktop switching because it seems to crash when I switch desktops very fast (my normal workflow is to have full screen windows, many virtual desktops and change them with keyboard shortcuts, I even manage to change a desktop and then change to another before it finishes drawing in the first one this may be the issue at hand). The dump backtrace seems to be very detailed so I hope this is helpful, please let me know if you need any other information. Thanks for your help.
