The fix in nouveau will be "remove glamor integration" and "fail to load for
GM107+". But we haven't fully decided on that *quite* yet. And I have an EXA
impl in the works for GM107, so perhaps we'll use that. TBD.

The problem that you're seeing is with glamor, and they changed the way font
rendering was done in X 1.17, which is why I'm suggesting you use that.

Separate from that, nouveau's integration with glamor is totally fubar'd and
should be removed, as per the above, but that has nothing to do with any
misrendering you might see. For example perhaps you might observe the lack of a
GLX_ARB_create_context_profile. This is a symptom of DRI2 support basically
missing, which is going to cause major problems.

Since nouveau's integration with glamor would be no different from
modesetting's integration with glamor, might as well just use that directly...
[There are one or two things nouveau can still do that modesetting can't, but
those differences are in the process of being eliminated.]
