[TW] No video in certain programs since upgrade of Mesa packages

Since the latest upgrades of the Mesa drivers, I have not been able to playback mp4 video files in mpv or web browsers (firefox). The audio channels work OK, and not every video viewer is affected, eg. VLC and Dragon can playback both video and audio. My video card is a Radeon RX 550 / 550 Series, system is Tumbleweed, display is wayland. Interestingly the same thing happens with Kdenlive. When I add a clip, only the audio channel is editable, the video channel is not loaded/available. Is this a known problem? Any suggested solutions? -- Bob Williams No HTML please.
