P: Inaccurate selections with Radeon graphics cards on Mac OS

Doesn’t mean much if you have to pay hundreds of dollars for an upgrade just to fix a bug. Classic.

We have a couple of workarounds for Apple driver bugs in CS6.

Apple is slowly fixing driver bugs in 10.7, but hasn't gotten them all yet.

I just tried out the Photoshop CS6 beta on my MacBook Air, and the bug appears to be fixed or worked around, because selections are dead-on, with or without OpenGL. This fix, plus the other additions to CS6 (in particular, the Layers panel improvements) will make this a must-have upgrade for me!

This is pathetic. Eight months since being reported, and no solution in sight. I have the same problem on a mid-2009 17" MacBook Pro. Marquee selections and slider adjustments are both unreliable. This is completely unacceptable. To top things off, the only reason I upgraded from CS4 to CS5.5 late last year is because, at the time, Adobe said you would have to pay full price to get CS6 if you weren’t upgrading from CS5.x. I know Adobe has since changed course on this (thankfully) but I’m still out the roughly $500 I spent for the upgrade and will have to spend another $500 or so to get CS6, which will hopefully fix the issue. No other graphics app on my Mac has these kinds of problems. Seriously, screw Adobe.

just turned off my OpenGL and it is working much better...too bad, cause now the program isn't as smooth

Having the same issues - switched from pc to mac and now I want to go back 😞

OK, Apple has not yet fixed all the video driver bugs on MacOS 10.7. Please let Apple know that this is important to you, so they'll give a higher priority to fixing these bugs.

Now that's a new one.
Zoom, make multiple selections, move document to the left or to the right.
And voila :-)

AMD Radeon HD 6490M
MacOSX 10.7.3

Are any of you getting this with other tools? I'm experiencing all the above, but also something similar when moving layers http://feedback.photoshop.com/photosh... Am wondering if it might be related.

Well, I just did the same. Let's just hope it's one of the priority bug fixes in Apple for the upcoming release.
