Comment 51 for bug 681915

Good find John. We'll be uploading mesa 7.10 within the next week or two. Sounds like this patch will be included in 7.10, so probably easiest if we wait until that release is in natty, rather than adding it as a patch. Meanwhile anyone with this issue can run xorg-edgers or the patched PPA if they want to eliminate the corruption and testdrive the fix.
