While typing code, ST2 suddenly stop refreshing the screen and the all UI looks freezed with an high CPU load (>100%).
If I wait few seconds, CPU usage get normal but ST2 display is still freezed.
But the strange point is that it's just screen update that is blocked. If I click on tabs, the window title is changing normally. And if il close the window and then restart ST2, I get in current editor pane all text entered while I was freezed.
From my observation, the "high cpu" can occur when ST2 decide to rescan my project files (bug one, 4936 files, 19000 without project exclusions) or when I activate some CPU consuming packages like SublimeCodeIntel.
I search in ST2 command line help but I didn't found any debug options in order to provide more accurate information.
The good point is that ST2 session recovery works just fine and I never lost any modification, event if I didn't save files I was working on (impressive !), but this bug can occur every 1/2 hours, which is kind of very annoying.
