Thanks Chris. It is safe to assume XMir will always use scanout buffers,
so long as the multimonitor layout doesn't have any overlaps.

[intel] Bypass mode makes the cursor break up into horizontal line
artefacts

Bug description:
Mir's bypass mode makes the X cursor break up into horizontal line
artefacts. I can see some pixels updating where the cursor should be,
but not all of them.
There's a flickering ghost of where the mouse pointer was just a
moment ago, comprised of small horizontal lines.
I've *heard* this is an intel-specific bug due to particular caching
behaviour of intel graphics, triggered by bypass (but only seen when
bypassing XMir surfaces, not other Mir surfaces).
WORKAROUND:
1. sudo -s
2. cd /usr/sbin
3. mv unity-system-compositor unity-system-compositor.bin
4. Now create a new file "unity-system-compositor" with:
---8<---8<---8<---8<---8<---8<---8<---
#!/bin/sh
export MIR_BYPASS=0
exec $0.bin $*
---8<---8<---8<---8<---8<---8<---8<---
5. chmod 755 unity-system-compositor
