It doesn't support OpenCL images (requiring buffers only) and while we did work around that, we found the OpenCL/OpenGL interop so buggy that we disabled FxPlug hardware rendering for these cards/OS (instead transferring from host memory to the card). AMD 6xxx cards in 10.7 had issues (something I found with local memory) but an update seemed to fix that.

This email sent to site_archiver@lists.apple.com In some cases (in this case, D1) the input and output bitmaps are different sizes. The input image was one line taller than the output image. Since I assumed they were the same size, I was doing all the processing at the input size, and when I tried to read it back to the output image, it barfed. Funny, I had solved this problem before, but as this is all new clean code, I didn't incorporate the fix. Need to keep track of all of these little gotchas somewhere.
