That just means the problem is a software rendering fallback path, but it
doesn't show which one. You'd need to make sure at least the X server binar=

are compiled with -fno-omit-frame-pointer and have debugging symbols.

Not sure, but my guess would be

That would be interesting.

I can't predict the future, you'll have to nominate it and see. :)
