Hi,
     hat would happen if ParamBufferSize is too small, when I draw a mount of triangles using OpenGL ES 2.0 ?

I have encountered a problem :
triangles drawn at the back, seem show in frames, then disappear in next frames, and then show again.

A friend told me that itís because ParamBufferSize is not enough. But I googled parameter buffer, still have no idea why this happens.

Should I cut down the size of VBO? or DrawCall?

Please help.
Thanks!
I didn't find the right solution from the Internet.
