Robert, can you explain how did you come to that conclusion? Xorg.0.log
attachment shows that glamor is used, DRI driver loads fine and according to
glxinfo HW renderer is being used. AFAICT this bug has nothing to do with xv
acceleration or with radv vulkan. In fact I cannot see anything that would
prove that this is not our bug.</pre>
