[android-developers] Vertex buffer object corruption on MSM720xa

Hi there,

i was refactoring some of my code today and wanted to minimze buffer
object binds. My use case is it to bind a vertex buffer/index buffer
pair once and batch up rendering as much as possible. Each batch is
uploaded to the currently bound vbo.

This works as expected on all tested devices (Nexus One, Droid,
Samsung Galaxy) but fails on the HTC Hero with stock Android 1.5. I
haven't updated the Hero to test exactly that kind of problems.

I have compiled a small in depth description with a reproduceable test
example. Both can be found at:

http://www.badlogicgames.com/wiki/index.php/Severe_Bug_Updating_Already_Bound_Buffer_Object#Sample_Code

I consulted with a couple of people whom i consider OpenGL experts and
they all agreed that the way i handle the vbo/ibo is indeed correct
and standard compliant.

It would help if some people with an update Hero could try it out and
see whether the problem persists.

Should i file a bug on the Android bug tracker?
