--- Comment #16 from Jason Ekstrand <[email protected]> ---
I was looking at something almost completely unrelated and I think I came
across the root cause of this bug. Currently, XWayland does not advertise
support for any multisampled visuals. You can reproduce this trivially with
"glxgears -samples 4". Hidden in comment 13 is this nugget:

I think the root cause here is that XWayland loads swrast for indirect GLX
instead of figuring out which actual DRI driver to load. Since swrast does not
support multisampling, we get no multisampled visuals. I don't really know the
internals of XWayland enough to know how to fix that problem but there it is.
