If you're talking about vsync, the idea is to have no break at all (the buffer should be changed while the screen takes a short break) If you have a tear line despite vsync is enabled, that means that it doesn't really work - and if the tearline shifts with the version that very likely means that the subbuffy copy can not be performed during the retrace and the only working approach is a buffer swap, see bug #307965 Reply at: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1061073/comments/43 ------------------------------------------------------------------------ On 2012-10-15T16:41:08+00:00 ValdikSS wrote: This type of tearing is typical for Intel HD3000. There is no way (I don't know any) to bypass it in KWin, but it can be bypassed in GNOME with some Clutter parameters. So, there is a tear line in 8.0.4, but it's on the almost top of the screen, and with 9.0 it is much lower, almost in the center. And I got another bug, just restored minimized window of opera browser and it didn't repaint anything. I have clicked on some tabs and nothing happened, minimized and restored again and it was on that tab that I clicked last. It never happened on 8.0.4.

I yesterday installed Kubuntu 12.10 on an USB stick and tried current master in OpenGL+EGL mode on my Intel hardware. It showed the same behavior and my guess it that it picks the wrong EGL driver.

Pushed by fredrik into branch 'KDE/4.9'. kwin/glx: Avoid MSAA configs in initBufferConfigs() It appears that we're accidentally choosing an MSAA config with the Intel driver in Mesa 9.0.
