I suspect that this patch simply uncovered an existing bug with spilling. Both the fragment and vertex shader spill heavily. I've modified simple.c to remove if statements from the fragment shader. After that the fragment shader doesn't spill, but the test still fails. Reducing the number of varyings to 108 allows the VS to now spill and then the test passes. More investigation needed.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
