I have been getting this error at least once a day. Once it happens, I usually just close and ignore the notification. I restart my computer in the morning sometimes, and it happens again. I encounter weird window behavior once this happens, such as clicking on the window in the task bar and it not maximizing, or maximizing behind all other windows. Also, ALT+TAB doesn't work sometimes.
