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.=20
The video is fine when the default (Ubuntu provided) video driver is used.=
=20
After the latest (18.50) AMD video driver (amdgpu) is installed (and comput=
er
is rebooted) this attached/linked video displays in bright colors.
See attached example screenshot of video issue/properties. I will try to at=
tach
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 10b=
pc ?
)
<application name=3D"Default">
<option name=3D"allow_rgb10_configs" value=3D"=
;false"/>
</application>

It seems like this issue is maybe the same as this one associa= ted with Intel driver here - https://bugs.freedesktop.org/show_bug.= cgi?id=3D104536 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 caus= ed 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 iss= ue could be, but mesa was mentioned in a similar bug report (https://bugs.launchpad.net/ubuntu/+source/gstreamer-vaapi/+bug/176= 7312).

Most of the time, if disabling allow_rgb10_configs works aroun= d 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 applicat= ion using a pixel format that can't work). It most certainly isn't a kernel driver issue, so reassigning to Mesa for n= ow. Please attach the output of vainfo when the problem occurs.
