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 Touch seeded packages, 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 Status in gstreamer-vaapi package in Ubuntu: Confirmed Status in mesa package in Ubuntu: Confirmed Bug description: Ii've found a bug on Ubuntu 18.04 (other distros, as fedora 27, debian stable, debian testing) aren't affected).
