P: Floating windows are sluggish compared to docked tabs on MacOS 10.10 Yosemite

[Uri Kirstein]

On my brand new Macbook Pro, in Photoshop CC (latest version), In Docked/Tabbed windows dragging objects around (like dragging a small red circle around a new document) is fast and smooth like liquid. Problem: On Floating windows however, it is very sluggish with rough movements (in comparison to tabs). And I always use floating windows. Can someone please help me resolve this so I can use my new Mac with Photoshop?

I also tried changing all the Use Graphics Processor advanced settings in performance (testing on new windows each time) and it didn't help this.

Do you have an 3rd party Extension panels installed?

Try restoring your preferences: http://blogs.adobe.com/crawlspace/201...

If you do restore your prefs, please save a copy of your existing prefs in case they turn out to be the culprit. Having the bad prefs can sometimes help us track down the issue.

This is a fresh new install on my new MacBook Pro 2.5ghz 16gb ram that I got for Photoshop use and would return the mac if this can't be fixed so I need to know what you guys think either way. I do not have any extensions or plugins just a raw install. I did try resetting the prefs file before posting as well. Please let me know how we can resolve this. A phone call maybe or whatever you think.. Thanks in advance! - Uri

And I fully appreciate any help you can offer me on this. You guys helped me through a similar issue years ago on my PC when GPU support came out.
