I have some new developments on this issue. Apparently if i turn on "reduce transparency" in Accessibility it gets better. If i have one or two windows open it's pretty fluid but if i have more than 3 open windows it gets choppy again. Funny thing is if i press exposé with Safari or Mail "selected" it's choppiness ****, even with very few running open apps on screen.

Any ideas?

Thanks for your reply Volkward.

On this side everything was fine until i updated to Yosemite. I just tested opening many finder windows, transmission and vlc. Everything ok, it just sometimes slips a frame with all these but it's pretty fluid. As soon as i open apps like Safari, Mail or Sunrise the choppiness frenzy starts. I'm aware of the buggy WindowServer process and been following that thread. Tried the fix suggested with no luck but bumped into a strange behavior on the way. Every time i repair disk permissions in safe mode the same permissions are repaired and everytime i go back the same permissions are still corrupt. This (image below) is what my disk utility always repairs no matter how many times i repair them. To get things a little weirder, if i follow the fix suggested in the other WindowServer related thread and reset SMC and PRAM after repairing these permissions, my computer just turns itself off somewhere half the way of the start chime. Sometimes it behaves like this even if i only repair these permissions and reboot without resetting SMC and PRAM (but mostly when i do these). After this i just turn it on again and it usually boots fine, though one time it remained turning itself off a few more times before i could boot normally.

ps. my mini display port is fried, do you think this could be related and triggering the bug?

The permissions that it repairs are installedPrinters.plist and displaypolicyd, it seems that they get corrupted every time i boot my computer. And yes i've been following that thread and the fix doesn't work for me.

My display port is fried since i had a problem with a alesis audio monitor that had a faulty power supply which wasn't very stable. I was using my iMac as secondary display to my Macbook, which had the audio monitor connected to it through an external motu soundcard. Everything suddenly turned off and it fried my motu main outs and my display port in the way. So yeah, don't know what is actually fried but it is mechanically damaged. Even so, this happened a while ago and i never had any other issues that could be related so far.

Yes, i hope the update fixes this though i think it won't till 10.10.2 or 3.

ds10320, in my case turning off transparency helps a little but it is definitely an issue of extreme cpu usage and memory leaks that apple should solve asap. I'm only affected by the memory leaks and there is a thread that as a possible fix for these issues, Volkward posted it here a few posts before. Try it, it might work for you.

Guide: How to solve Yosemite memory leaks and CPU usage

What's causing it seems to be a system process called WindowServer and the only way around it is the fix suggested in this thread which not always works. Many people claim they have this issue after connecting a second display, if you're using a second display try to disconnect it.

Good luck, hope it helps.

I guess there isn't much more to do then wait for an update from apple that fixes these issues. One of the problems is memory leakage and i've red reports from people who have 16g of memory and have almost all memory used up. In my case, as soon as i open apps like Safari, Mail, Sunset and a few more my available memory simply goes away for no apparent reason. I have all my 6gb of memory used pretty much all the time, with or without heavy app load.

Not sure about newer models though.

Hope this gets solved soon, it's affecting my productivity big time and i can say it's one of the worst .0 releases of OS X i've witnessed so far, at least in my apple computers.

Hmmm, this actually helped a lot. The choppiness didn't go away completely when i have many open apps and memory leaks still persist but it actually improved the choppiness issue and system performance very much.

Thanks D.
