GPU: IVB 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) CPU: core i7-3667U OS: gentoo Today I updated xorg server to 1.15 from 1.14 and video-intel from 2.99.910 to 2.99.911 alongside a bunch of xorg, proto and similar packages. Mesa was already at 10.1.0 and was working well until this update (very well I should say). I can downgrade video-intel if needed, Xorg is a bit more complicated. Symptom: I use KDE (4.11.5 atm), with vsync enabled in KWin. I use the setting "full screen repaints", which is the only one giving me tear free VLC. From the update I get something like 5 fps fopr screen updates. glxgears still reports around 60, even if what is displayed is obviously less. Guess the compositor is in the middle here as well. Using the automatic vsync setting, will trigger the issue only when KWin choose to enable vsync, so it is harder to reproduce. Disabling vsync cause no issue at all.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
