Bah, humbugs. OK, this time I'm definitely not able to reproduce the issue so far. Maybe it will some extra time - hard to say now - but before it has took me just minutes to get the issue visible. intel_gpu_top now shows only few lines busy to 1% during scroll. The bad part is - while before I've been getting 3.7Mchar/s in x11perf -aa10text - now it's like 1.3Mchar/s so significantly slower. So the question here would be - isn't the corruption based on triangle surface size ? So i.e. GPU is able to process a lot of small ones - but has bug with bigger ones ? Maybe a cheap test would be to flush when some longer triangle edge is pushed in ?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
