P: Inaccurate selections with Radeon graphics cards on Mac OS

After installing Lion, selections with the Rectangular Marquee Tool generally are reduced by one pixel when the mouse button is released. For example, dragging a 25x25px square results in a 24x25px selection.

Yup. I was right. 🙂

What we're trying to do is solve the problem, and stop having people yell at us about problems that we didn't cause and can't do much to solve.

I'm getting the feeling that Adobe support is not interested in making sure their customers are feeling positive about the communication they're getting. -Jackson

At home now. My card at home is: NVIDIA GeForce 9600M GT 512 MB ...Same problem as on the Radeon.

Jackson - how can we have a conditional for a fix in a driver that hasn't been released yet and might get broken in yet another driver update?

Thanks, Michael. My Mac Pro has an NVIDIA GeForce GT 120 512 MB. My iMac is either the Radeon HD 5670 or 5750. (it's at home, so I'm not sure which.)

Chris-

Your assertion that I'm complaining about an Apple driver bug may very well be true, but is both flippant and unhelpful. Unfortunately, unlike JacksonC, THAT is what I have come to expect from Adobe recently.

First off.. Thanks for working on the problem. I've always applauded Adobe for usability and precision.

> the fix will result in an offset

Really? Surely you could use a conditional.

We've reproduced the problem in other applications. But it's likely that Photoshop is the only application you are using that uses the Cocoa APIs and OpenGL where you can see the offset.

We've been working with Apple on these issues for a couple of years, but new bugs keep getting introduced with each OS/driver update. And if we work around the bug, then the fix will result in an offset as well.

Same here. Suspect it's the same issue.
