Not to me ;) But yes, TexGen is currently pretty much completely broken. Fixing it would require a larger overhaul of some parts of TinyGL.

VBO "kinda works" but not with failures: Just right the level starts and having TGLDEBUG enabled you can catch a suspicious error about "disabling vbo support" of something like that.
Do you mean
Disabling VBO rendering due to incompatible parameters? If so, that happens if the array format is not GL_FLOAT, or if a misaligned offset/stride has been given. It's only disabled for that specific array, and only for as long as it has incompatible data assigned to it.

And reallocating new buffers locks up for seconds the game. Glitches and so on in game I don't know if they are related to vbo's or not.
Have you confirmed that the second long lock-ups are due to VBOs? Or is it just a hunch?

I had to use a bit of Google-Fu, but I'm guessing you're referring to
this example code on GitHub. I tried it out, and indeed, when switching to VBO mode on MorphOS, the pyramid disappears. I then tried the exact same example on Linux, and when switching to VBO mode, the pyramid also disappears there. So I think MorphOS is actually doing it right in this case ;)
I rarely log in to MorphZone which means that I often miss private messages sent on here. If you wish to contact me, please email me at [username]@asgaard.morphos-team.net, where [username] is my username here on MorphZone.
