Hey i got this problem
when i draw something in the vertexbiffer like a cube or something it works fine.
and i use matrices to rotate it.
it works good most of the time but sometimes i only see a small part of it, and it''s almost a checker pattern that you can''t see ...
most of the times it goes well
and i''m pretty sure i''m doing it the same as i did when it worked.
like releasing everything in the shutdown and all that.
