That seems fine as a solution. It may still be interesting to figure
out whether test_il_append_aligned() or test_instanced_draw() is to
blame here though. (E.g., if you queue multiple instances of either
test_il_append_aligned() or test_instanced_draw() does that also
introduce failures? Is there any particular part of
test_il_append_aligned() that introduces failures in
test_instanced_draw()?)
