Screenshot of grain

After testing on my Radeon HD 4870, 6850, 7950, and R9 270X machines, when enabling SSAO in Tesseract on the RadeonSI machines, the SSAO produces a very grainy visual effect while R600-based machines renders fine, besides TGSI bugs being spit out to the terminal.

 Confirming this with Radeon 8400 / R3.

If you could capture an apitrace demonstrating the problem, that might be useful.

 This seems fixed in current git 10.3-devel :).

Yep, seems fixed, thanks for the followup.
