I hit this bug on Fedora 28 when using a third-party mesa build. Here's the ~/.drirc I used to fix this:
<driconf> <device driver="radeonsi"> <application name="totem" executable="totem"> <option name="allow_rgb10_configs" value="false" /> </application> </device> </driconf> This also fixed the timecode in Totem showing strange, rainbow colors, caused by the same thing. Repeat the application section as required for each program affected. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1767312 Title: [radeon] Totem with gstreamer1.0-vaapi and Xorg: wrong color on H264 videos To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gstreamer-vaapi/+bug/1767312/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
