FWIW I see it too.
I don't think it's a wxWidgets bug - this is failing in code in
loch/lxR2P.c which makes calls to the glx layer which is a lower
level API than wxWidgets. It could be some sort of interaction
with wxWidgets OpenGL support though since it's effectively going
behind wxWidgets back.
I'm not sure why loch doesn't just use wxWidgets OpenGL support - that's
what aven does and that still works in current Debian unstable.
You probably want Martin or Stacho rather than me - they wrote this code
and presumably understand the API it's using and why.

That's a development release, so not something we can package for Debian
- every new version would require rebuilding nearly 100 other packages,
and potentially updating them all for API changes. We have to do that
for a new release series (e.g. moving from 3.0.x to 3.2.x) and it
typically takes 6 months to a year to complete.
I've not tried building packages of 3.1.x so I can't offer any useful
advice there. But I doubt it's the answer anyway.
Cheers,
Olly
