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.</pre>
