That explains why both aa and rgb glyphs are the same speed as well, and why the impact of the extra damage tracking for a compositor doesn't affect performance much. So I guess the characteristic of the slowdown on your machine is going to be best modeled by rgb24text. And that as far as I can see, everything is in order with your hardware - it just seems to be a particularly brutal rendering path for your GPU.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
