This might be possible duplicate of: https://bugs.freedesktop.org/show_bug.cgi?id=104597 I can reproduce this too on openSUSE with Mesa 18.1. The issue itself is exposed only on Radeon driver not on intel/nouveau. The workaround of course works, but I think there must be some bug in Mesa radeonsi code as the intel/nouveau both manage to play stuff properly using the libva and the conversion to opengl.
