Um, I did write "add", not "remove". :-)
Adding -shm would disable glamor.

Ok, so there is at least GLSL support in theory. Much better.

This just means that GL apps under Xwayland would be software rendered, but I'm
not sure it implies anything about Glamor.

Looks like I can't make sense of the trace. Maybe I can't use 'perf report'
right?
All I see is a huge number of lines like
1.47% Xwayland ^E [.] 0x0000000000211da8
and some rare others.</pre>
