[Intel-gfx] [REGRESSION] [SNB] Scaling in VLC 2.2.2 does not work with Linux 4.6-rc2

[Martin Steigerwald]

Hello!

As I don´t know how much you use or look into the bug tracker, I just ask here 
as well.

Any idea about this one?

Bug 94978 - [SNB] Scaling in VLC 2.2.2 does not work with Linux 4.6-rc2 (edit)
https://bugs.freedesktop.org/show_bug.cgi?id=94978


Paste from report in case you prefer handling by mail:

Yesterday I took more than one hour to persuade my X86_64 Debian GNU/Linux 
Sid/Experimental system to play back a DVD. VLC 2.2.2 on that machine didn´t 
scale the video to the screen size. Also any manual zoom options did not have 
any effect.

After trying a bunch of other media players which have broken DVD menu support 
or other serious issues, I finally rebooted into a 4.5 kernel and there 
scaling in VLC 2.2.2 worked out of the box and we were finally able to watch 
the movie.
