Can't reproduce this any more. Mir now has double buffered clients as well as double buffered compositing so the bug should be more visible, not less. Although vivid also just got updated to Mesa 10.5 which is where I would expect a fix to come from. Seems to be fixed, probably by recent Mesa/kernel updates.
