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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
