[Octave-bug-tracker] [bug #54762] Using fill with 1000 vertices crashes octave

[Georg Wiora]

Follow-up Comment #11, bug #54762 (project octave):

Surprisingly the problems do NOT arise when running octave from a windows
_cygwin-installation!_ The test with 1000 vertices repeatedly succeeds. I
tried to call the test with 5000 vertices not producing a crash:
++
fill(rand(5000,1),rand(5000,1),[200,217,238]./255,'edgecolor',[0.7,0.7,0.7],'linewidth',0.5);
--

It has a loooong execution time (20 minutes on i7) and needs a loooot of
memory (~2.5 GByte) but it does NOT crash. After building up the memory
structures (~8 minutes) one CPU core keeps running with 100% but no output
appears. There is also no change in memory usage.

GPU usage statistics for octave process while running the command says:
* Dedicated GPU-Memory: 8.2 MByte
* System GPU-Memory: 79.5 MByte
* Committed GPU-Memory: 105.7 MByte

I think this shows that the problem seems to be located in some windows-only
glue code or in some windows specific limitations of opengl.

P.S.:
More efficiency in openGL rendering would be heartly welcome.
