I've been using OS X Yosemite for a few days now, there aren't a lot of problems, but this bugs me - VLC and Transmission file icons (.mkv, .avi, .torrent) doesn't have any icons, just plain blank page. Are the apps outdated for Yosemite? Or is there a way to fix this? Haven't really noticed this behavior with other apps rather than those two. Deleted all Cache folders: /Library/Caches /System/Library/Caches /User/Library/Caches rebooted, and the problem is gone.
