Comment 18 for bug 1460149

OK, with some fiddling I can confirm the same bugs are visible in Mir's demo servers (from package mir-demos). So Unity8 is not a problem.

I can now also see what the problems are:

1. Seeing double: This is SDL incorrectly telling the app that a 16-bit pixel size is supported. It is not supported in Mir.
2. Wrong colours: This is also SDL incorrectly telling the app that it can use 16-bit colour. Mir only supports 24 or 32-bit colour right now.
