There is no difference with this. FWIW I found another regression with this kernel that is caused by the same commit. Maybe regression is the wrong word, as there was already an issue, just it's worse now. I will file a separate bug in time (was planning to do new xorg and retest first) but in summary - Unigine Valley always did have some 1/2 to 1 sec pauses ever since I could run it, first on HD4890 and now radeonsi R9 270X. Since this kernel commit they are 2 to 4 times longer - also unchanged by patch. Strangely, if I use ffmpegs x11 grab to make a recording @ 30fps they become short again.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
