--- Comment #19 from Kimmo Kinnunen <kkinnunen at apple.com> ---
This is most likely due to the same root cause as bug 231607.
The test case appears to ramp up the amount of vertices drawn with drawArrays.
This causes the conversion attribute buffers to be re-allocated for each draw.

To work around the issue, you could try to store each vertex attribute in a separate buffer.
