> Thanks. I am pretty sure the GLSL compiler fails to unroll a loop.

I think the shader that failed to compile is a different shader that we use for
scaling textures for the taskbar thumbnails. The blur shader doesn't use loops.

But I have attached a piglit test that I hope can be used to reproduce the bug.

I don't have an R300, but the blur shader works for me with R600C and the new
GLSL compiler. The piglit test fails with R600G, but not with the symptoms
described in this bug report.
