So I assume now the rendering happens to some off-screen memory - which is then transfered back to screen with errors - and refresh doesn't help with this case. (and it's a bit different then during typing text into input box). Another probably unrelated comment could be - even when 'glxgears' is running in parallel - the visual errors still happens during typing of this text. I'd have expect the glxgears manages to 'overfill' GPU queue (since it's rendering ~1300FPS with default window) also the flushes are probably completely different. And - there is no observable rendering error in gears window - only Firefox seems to be exposing them.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
