Bug#778991: conclusion

2015-03-01 Thread Tim Krieger 
I opened a bug report her:

https://bugs.freedesktop.org/show_bug.cgi?id=89291

-The problem affects only ivybridge.

-The problem is gone after activating sna acceleration. With
-intel-2.21.15 from testing I recognized other bugs (e.g. big shadows
under the nautilus window).

-With -intel-2.99.917 from experimental only activating TearFree
(perhaps i915.semaphore) results in smooth animations.

I think it's not a major but annoying bug. All machines with ivybridge
are infected. There isn't a solution with the actual driver in stable,
testing or sid. The only workaround is fiddling around with experimental
and some modifications in /xorg.conf.d.

Bug#779062: Patch

2015-02-25 Thread Tim Krieger 
I reported this bug to gnome bugzilla.

https://bugzilla.gnome.org/show_bug.cgi?id=745063

Milan give me the advice to this (closed) report:

https://bugzilla.gnome.org/show_bug.cgi?id=729733

It seems to be the same problem.

You can find the patch here:

http://sourceforge.net/p/freeassociation/code/1150/

I didn't test this yet.

Thanks, I can try it. But: The animations in Gnome shell in Debian are
smoother than in other distributions like Fedora or Archlinux, which are
using a recent driver – I tested a lot configuration like tearfree or
sna. 
It sounds crazy but the old Debian driver in combination with UXA
seems to increase animation speed. I'm a little bit afraid to change the
xorg-driver.

Okay, after generating /usr/share/X11/xorg.conf.d/20-intel.conf with the
following content...

Section Device
   Identifier  Intel Graphics
   Driver  intel
   Option  AccelMethod  sna
EndSection

...the problem is solved. This workaround results in little tearing.
Adding the tearfree option doesn't help and results in stuttering.

So ist definitly a video-intel bug.
