--- Comment #10 from Osbios <osbios at web.de> ---
ok forget the errors I get except the freezing.
The driver was just ranning our of memory because I hat no glFinish and gave it
no time for the actually copy/deleting of the buffers befor creating new ones.

There is no exact buffer size that causes the freeze.
If I try often enough I managed to kill it with a 123032 KiB buffer so far.
