P: Slow UI when using Mac and Custom Display Profile

A recalibration did NOT work for me... I think it is hit or miss.....

“My core belief is that if you're complaining about something for more than three minutes, two minutes ago you should have done something about it.“ -Caitlin Moran

Just report issues, properly, and move aside:

With respect, without complaints there would have been no fix. And yes, bugs happen, it's just that Adobe has cornered that market for ear plugs.

Yes, at least it has worked for me. I did a bunch of testing, switching back to old calibration profiles and the only profiles that worked are AdobeRGB 1998, and sRGB, and then any new profiles since v10 was released.

There is a bug. It's pretty rare in that no one inside Adobe or outside within beta (myself included) ran into the bug. Bill is mostly right and of course Adobe didn't go out of it's way to release the bug. It will get fixed, everyone smart enough to back up prior to update can revert to the last version and get back to work.

No software is bug free. 

Complaints will not speed up the fix! 

Are you saying that a simple recalibration fixes the problem? It's so easy to do with ColorNavigator on an EIZO, I will kick myself around the room for not thinking of that if you are right.

I wasted a full day messing around with every conceivable fix - except that one. I will try that tomorrow. Thanks.

It's good to be humbled occasionally, thanks for the feedback. 

Actually @bill_3305731, because of this post, Adobe have been very helpful. They reached out and signed me up to their beta testers program and trying the future release along with other beta testers. My video card is indeed supported and all counter arguments you made have proven to be incorrect. We are helping Adobe work through this issue. Thank you for your input.

See Belinda, there are people here who can help you when you ask instead of ranting. 

Belinda, I found that re-calibrating my screens fixed the speed issues. Been running 10 for weeks now.
