Seeing visual corruption in totem after installing amdgpu 18.50 in Ubuntu
18.04.1.  Not present with default OS provided video driver.


I've just tested opening a specific video when my Ubuntu 18.04.1 LTS system
does not have the amdgpu driver installed from AMD, and AFTER the driver is
installed. 


The video is fine when the default (Ubuntu provided) video driver is used. 
After the latest (18.50) AMD video driver (amdgpu) is installed (and computer
is rebooted) this attached/linked video displays in bright colors.


See attached example screenshot of video issue/properties. I will try to attach
more pics if possible.


If I add the following to the /etc/drirc, the issue disappears.  The word is
that this indicates there is an issue with rgb10 support (10 bit RGB or 10bpc ?
)


        <application name="Default">
            <option name="allow_rgb10_configs" value="false"/>
        </application>

It seems like this issue is maybe the same as this one associated with Intel
driver here - https://bugs.freedesktop.org/show_bug.cgi?id=104536

But I may be misunderstanding.


I will say that the AMDgpu drivers appear to have usability issues in Ubuntu
18.50, as my primary intent is gaming, and there is almost no possible
configuration without major side effects. I did try amdgpu-pro,  which caused a
whole other set of issues.

I also edit videos almost daily. So I notice issues immediately.

Let me know what detail you require to proceed.  I'm not sure where the issue
could be, but mesa was mentioned in a similar bug report
(https://bugs.launchpad.net/ubuntu/+source/gstreamer-vaapi/+bug/1767312).

--- Comment #3 from Michel Dänzer <michel@daenzer.net> ---
Most of the time, if disabling allow_rgb10_configs works around an issue like
this, it's a bug in the application or a higher level library above Mesa.

However, some people are claiming this is a Mesa issue (something about not
(correctly) supporting some VA-API functionality, resulting in the application
using a pixel format that can't work).

It most certainly isn't a kernel driver issue, so reassigning to Mesa for now.

Please attach the output of vainfo when the problem occurs.
