Dear stijn,

please file a bug report on http://savannah.gnu.org/bugs/?group=octave
Please mention also the Windows Version used and 32/64bit.

I can confirm your problem using WindowsXP Pro 32bit with
Octave-3.6.2-mingw and the fltk toolkitas graphics backend.

Using gnuplot all works fine. Please add the output from

$ graphics_toolkit

And

$ plot(rand(10000,1))
$ print("test.png","-debug")

switch to gnuplot to check if this work:

$ graphics_toolkit gnuplot

And try it with gnuplot:
$ plot(rand(10000,1))
$ print test1.png

gswin32c has problem when using antialiasing on your testcase,
you could also disable antialiasing:

restart octave, then
$ plot(rand(10000,1))
$ print("test2.png","-debug","-GraphicsAlphaBits=1")
