--- Comment #6 from Michel Dänzer michel@daenzer.net --- This is probably because the Gallium textures which end up being scanned out are created without the PIPE_BIND_SCANOUT flag set, so they end up with a tiling mode which is not supported by the display engine. I can reproduce similar issues with weston, especially when making apps fullscreen, and I can work around it in the radeonsi driver by always creating textures as if the PIPE_BIND_SCANOUT flag was set.
