I have tested on my Radeon RX480, also AMDGPU drivers, git snapshot from 20180829 from Padoka PPA, and this bug occurs with Totem as well.
It should also be noted that the bug does not occur with mpv, either with vdpau or vaapi. ** Attachment added: "Screen shot of mpv plus vdpau and terminal output" https://bugs.launchpad.net/ubuntu/+source/gstreamer-vaapi/+bug/1767312/+attachment/5181987/+files/Screenshot_20180828_204917.png -- 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).
