Follow-up Comment #14, bug #54762 (project octave):

I could reproduce this in version 6.4.0 on the same machine that produced the
crash in 2018. No graphics driver updates have been applied. The test with
1000 vertices runs within ~10 secs. The test with 5000 vertices crashes
octave-gui completely and directly jumps into system debugger. There is no
console output.

After opening the debugger I got the following information

> Ausnahmefehler bei 0x000007FEDA14806D (glu32.dll) in octave-gui.exe:
0xC0000005: Zugriffsverletzung beim Lesen an Position 0x0000000059889000 

English translation:
> Exception at 0x000007FEDA14806D (glu32.dll) in octave-gui.exe: 0xC0000005:
Access violation reading address 0x0000000059889000

The call stack of the main thread may give a rough idea where this came from:

P.S.: Efficiency is still a topic.
