...t.edu> --- It appears that not all textureGather variants fail. Only nonconst and offset ones. (On my GK208 at least.) And the offset ones pass on GT215 (and it doesn't support the nonconst one - that requires ARB_gpu_shader5). The image that appears on the screen is the same independent of ST_DEBUG=noreadpixcache, but in the latter case, the test passes. Still investigating. -- You are receiving this mail because: You are the assignee for the bug.

...veau Product: Mesa Created attachment 98301 --> https://bugs.freedesktop.org/attachment.cgi?id=98301&action=edit apitrace of simple test program. Problem appear in shaders containing loops with conditional break when loop is not unrolled by nouveau. I checked emitted code with ST_DEBUG=tgsi NV50_PROG_DEBUG=1. Tested with Mesa 10.2.0-devel (git-475f5ff) from 2014-04-30. This bug exists for more than year, I first saw it in 2013-02. I think that artifacts appear in areas where is big difference in number of iterations executed for pixel before breaking from loop. -- You are recei...
