[regression, bisected, r600g] Wrong rendering of Bubbles3D screensaver
Last modified: 2011-07-10 10:33:03 UTC
Instead of looking smooth and nicely translucent some part of bubbles appear to be opaque. I've bisected and the commit that caused this bad rendering is:
- r600g: LIT: swap MUL_LIT operands to fix 0^0
This is on AMD Radeon HD 5750 and with XScreenSaver 5.14

[PATCH] r600g: LIT: clamp negative src.y to 0
Does this patch help?
Yes, with the patch applied the problem is gone. Thank you very much.
