Remotely displaying OpenGL hasn't worked well for many, many years,
and it appears that it will be going away once Wayland replaces X11,
so long term, you're better off switching to vnc or some other
remote desktop interface. In the short term, it does still work
sometimes, and when it does work, it is very good -- usually if the
graphics driver on both ends is from the same vendor. But, for most
people, the long term solution is still the best short term
solution.<br>
<br>
In your particular case, with a Linux server and a Mac client, both
sides could be buggy. On the Mac side, I would use the latest
version of XQuartz from xquartz.macosforge.org as the X11, try both
the latest stable release and the latest development release. If
that doesn't fix the problem, then my guess would be that the bug is
with the ancient version of Mesa that is installed on the Linux
server. The fix for that is difficult, you need to compile Mesa
from source, and set the LD_LIBRARY_PATH environment variable to the
directory with the compiled Mesa libraries before starting Chimera.<br>
<br>
Good luck!<br>
