Photoshop CC on Mavericks: Photoshop slows down/freezes often
Ever since updating to Mavericks, in addition to having the blank menus problem (see relevant thread: http://forums.adobe.com/message/5785359#5785359), I noticed that about once every hour or so, Photoshop will stop reacting to things (it's not listed as "Not Responng" though and there is no beachball or grey circles cursor). Sometimes it will go back to normal on its own, sometimes I can click on a different app and go back into Photoshop and it's fine, but sometimes this won't help. If I work on huge files (2-3 GB PSB files) then slowdowns get much more frequent to the point where I click on something, it freezes for 2 minutes, and then I continue working for a few seconds and it freezes again and so on, until I quit and reopen the file. This has happened a lot on large files, but the short slowdowns always happen regardless of file size. It's extremely annoying and far worse than the blank menu bug.
I notice that most of the time (if not always) I am using the Brush tool when this happens (this might be coincidence - I use the Brush a lot).
I can't yet figure out how exactly the process happens, but it only occured to me now that this may not be general normal slowness since it never happened before. I have 16 GB of RAM on a fresh new iMac so system performance should not be an issue, especially not on tiny files.
I will provide more info when the bug happens again, in the meantime, does anyone else have this issue? Any suggestions?
Also, no I don't have any dodgy programs installed. OS X Mavericks, Photoshop CC 14.1.2, and Wacom Intuos 4 Driver 6.3.7-3, plus some other apps that are necessary to run a computer nowadays (Perian, MPEG Streamclip, Flash, Java, and not much more (see screenshot).
