Yosemite + Radeon = Mouse Lag?

[sammyman]

So I have been reading the Yosemite forums about an issue which seems to have plagued my Mac Pro. I just removed a 7950 PC version which was giving me mouse lagging issues and replaced it with 2 x GT120's which seem to work fine.

So I'm wondering if this is more an issue with the fact that I was running a PC version card not flashed, not modified (resistor not removed) and therefore not running at 5.0 GT/s. Or is this a more broad issue with all Radeon cards?

It has nothing to do with flashed vs. non-flashed. It has everything to with with Yosemite vs. AMD.

Running Yosemite + 7950 Mac Edition here, no mouse lag so far.

Yeah, that's what makes it hard to track down I suppose. Not everyone has the issue.

I don't have a mouse issue with mine either. For me, this problem manifests itself as being cursor lag with typing into web-form text boxes. Like here while I'm sending this reply. I can type a full half sentence with no feedback on screen. It all stays in the buffer, then suddenly bursts into the box seconds latter. It's most annoying. With the exact same hardware configuration, I can boot into Mavericks and there is no such issue.

I have this issue as well, but only in Safari.

I had the "certain web forms annoying lag" on my 5.1 with msi non flashed 280X.

When I did a clean install it went away. I had always just upgraded the OS, but felt it was time to go clean and that solved this specific issue for me.

I really did a clean install—not a restore or anything like that.

I did that too, it was no help here.

There's another post about this from months ago, al to of us ATI / Yosemite people experience this.

It seems centered around Safari, def. on form inputs, but having a video playing in the background also produces it. It looks up the entire display output sometimes.

The issue was not present in Mavericks and is highly frustrating.

A clean install did not fix the issue for me either.

I'm running a GTX 780 so not affected. However, Apple released Safari 8.0.6 yesterday. Have you folks tried it?

Video in the background makes no difference for my machine.

Yeah, I've been running the update. Made no difference at all with regards to the text input.
