Since upgrading to 535 I've noticed that Rubymine seems to be running a lot slower. Activity Monitor often shows Rubymine using over 100% of the cpu even when it's not actually doing anything. At times it becomes unusable slow, it can't keep up with my typing for example.
I'm using a MacBook Pro, 4Gb Memory and a 2.4GHz Core 2 duo. Is there any more information I can give?
