3.6.4 and 3.8.0 are both deprecated.  As Dan said in comment #1, this has most likely been fixed.  If you can reproduce the problem with the 4.0.0 release candidate 4 then we can investigate further.  See ftp://alpha.gnu.org/gnu/octave/ to download a newer version of Octave.

Your sample code works on my system (Fedora Linux) with the development code for these three graphics toolkits:

graphics_toolkit ('fltk');
graphics_toolkit ('gnuplot');
graphics_toolkit ('qt');

This problem likely has been fixed.

When creating a histogram with the function hist(), the colour of the bars sometimes disappears. At another zoomlevel, the colours are right again.

Also sometimes the colour does behave random, creating coloured triangles on the screen.

tested on Windows 7 (Octave Release 3.8.0) and Fedora (Octave Release 3.6.4)
