--- Comment #101 from Pierre-Eric Pelloux-Prayer pierre-eric.pelloux-prayer@amd.com --- Created attachment 144948 --> https://bugs.freedesktop.org/attachment.cgi?id=144948&action=edit comparison screenshot
It looks like a DPBB/scissor interation issue.
The screenshot on the left is a replay of a faulty trace with dpbb disabled. On the right the same trace, at the same point but using dpbb.
The last executed commands are: glScissor(3, 3, 480, 144); glDrawArraysInstanced(GL_TRIANGLE_STRIP, 0, 4, 1);
As you can see, the purple area on the right doesn't honor the defined scissor area.
