You mean the colours look right but you have unexpected transparency? If
so, that's not entirely unexpected.
The bug for Mir demo servers doing that is bug 1423462. However I have a
hunch that Unity8 has the same bug (which has not been officially
reported yet). That would not be surprising as it's actually an OpenGL
limitation (the right pixel format does not exist in the OpenGL|ES spec)
and is slightly awkward to work around.
So there are two possible solutions to that:
1. Try to make sure your alpha channel (or "x" byte) is always opaque (255)
in the app:
e.g. glClearColor(0.0, 0.0, 0.0, 1.0);
2. Get the server fixed. Mir demo servers have bug 1423462 open for this.
Unity8 has no bug logged against it yet.
