I was having them, they were pretty bad. Everything works well on Mavericks though. I was wondering, for those who had GPU glitches, did the update fix it?
Time Machine is a mess when it comes to graphics.
No they are not gone, as worse as ever.
And honestly I don't think they will ever be fixed. It's just how OS X has been coded.
If Apple could release Yosemite with all these graphic jerkiness then I'm afraid to say that they find it very normal
I can confirm this on my rMBP. But TM looks fine on my 2011 iMac.
