Comment(by annakrat):

 I was running nviz on Ubuntu in virtualbox (Windows host) and
 interestingly, double buffering causes pretty bad flickering. When I
 comment it out in the code, it runs fine. When 3D acceleration is set (in
 virtual box), the flickering disappears. But double buffering also causes
 that saving image and rendering legend in 3D view produces just black
 screen (with or without 3D acceleration). I might add an option to
 settings to disable double buffering (at least on Linux).
