Flint locking up window manager
Just putting this here for the record, not expecting any changes right now.
We noticed on lid21nano (debian8) that the window manager was very slow / unresponsive (this had happened last week too but the machine was rebooted so didn't get to diagnosing what the actual cause was). This time i managed to kill all the running processes one by one to find the cause, and it looked to be flint. The flint window looked to be totally unresponsive but not using lots of cpu / ram, killing this process bought the window manager back to life. checkmk shows a few cpu peaks at about 13:00 (29/11) when i intervened yesterday. I don't think the bliss installation has changed recently, so shouldn't be the introduction of a new bug. Talking to @valentin.valls could be possible gfx driver issue? I dont think anything has changed on this machine recently
