Situating is changing continuously. I mean i forgot which font i used before. But i see now that it depends on font too: DejaVu Sans Mono is much faster then Droid Sans Mono or Liberation Mono. And depends on composting engine also: Now im on DejaVu Sans Mono 9pt and Xrender lags when OpenGL is fast. >Do the characteristics of the lag remain the same -- very longs waits whilst stalling for memory (GAM)? Looks like. But harder to acheive. And waits ms is lower. Hm. I caught total hang maybe because of using OpenGL or gpu-overlay so i had to restart. After restart everything little bit slower again. It seems i need to do all the window switch, font change magic again.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
