--- Comment #8 from wadev-cl+VPiYnx/0HWmgEVkV9KA@public.gmane.org ---
Now it became more interesting.
I "downgraded" to Jessie (clean install), 3.16.0-4, with

OpenGL vendor string: nouveau
OpenGL renderer string: Gallium 0.4 on NVD9
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.2
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

..and I still have the problem :/

The log messages are, however, different. I add some here should it help
anybody somewhat.

Starts with this:

        <pre>Now it became more interesting.
I &quot;downgraded&quot; to Jessie (clean install), 3.16.0-4, with

OpenGL vendor string: nouveau
OpenGL renderer string: Gallium 0.4 on NVD9
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.2
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

..and I still have the problem :/

The log messages are, however, different. I add some here should it help
anybody somewhat.

Starts with this:
