Comment 10 for bug 2037307

This issue also occurs semi-randomly when making normal touchscreen motions. For instance, sometimes I'll be scrolling through a webpage, the suddenly Firefox will un-maximize itself (turning into a normal window), and the cursor will get locked into the drag state. As per this issue, the system is then rendered inoperative until I kill Firefox (the active window).

This however, is not consistently reproducible, where as dragging from the top bar will cause the issue 100% of the time. It is by no means uncommon though, it is actually quite annoying to have my entire system freeze up semi-regularly and require me to manually restart Firefox (in fact, it happened while writing this comment).

I have also done some more testing.
- Minimizing the active window (using wmctrl) from a virtual console does not solve the issue.
- Starting a new window from a virtual console does not solve the issue.
- Consistently, the only way to resolve this issue is the kill the active program.
