<pre>The speckle looks to be a blend failure. It looks to be in the compositor as
the pattern seems to have some of the overdrawn content, which is why I suspect
that mesa is involved. At first I thought the speckle would be a cache
invalidate issue, but it doesn't actually seem to be wide enough for a
cacheline issue - so it may be a bad EU, sampler or killpixel instruction.
When you tried 9.2.6, what changed? Presumably the glxgears returned to normal?</pre>
