I've been playing with this a bit more and have some more notes...
- if in the sample, if you take out the glGetIntegerv and just set texdim to 64,
the artifact will be a bit larger and more obvious.
- if i use a separate texture id for each quad, everything looks fine.
- if i do a glFinish after each glDrawArrays() everything looks fine.
- it looks as if there's some sort of synchronization problem with
glTexSubImage2D. as if one can change the texture with glTexSubImage2D() while
a triangle is still being rasterized with that texture and it affects the
rasterization of that triangle. it seems one would want to wait until the last
glTexSubImage2D() was finished before allowing another one on the same texture
object rather than allowing them to clobber all over each other. not sure if
that's what's happening here, but it looks like it might be.
