Sounds like GL rendering might be to blame. Try --no-opengl

As above.

The last 2 are probably related to this one:

None of these problems have been reported by anyone who tested 0.10
before its release, but then again... AFAIK none of them tested Ubuntu
very thoroughly either.
(though I did quite a bit of testing on 13.04 myself recently)

FWIW: apart from the well tested platforms (win32, OSX, Fedora, some
CentOS versions), it even runs on OpenBSD (I've just verified) so I am
pretty confident this is mostly an Ubuntu only problem (yet again).

This can be ignored, there are no "python-numeric" packages available,
and this causes this warning in PyOpenGL.

Please try --no-opengl and see if that fixes most of your problems.
If so, please post the output of:
glxinfo
xpra/client/gl/gl_check.py
So we can blacklist the offending drivers - though I am tempted to just
blacklist all Ubuntu releases and give up on supporting that platform.
