Sure! Hmm… Would it perhaps be more convenient if I posted a version that didn’t apply my various custom shaders? A quick experiment suggested that the bug still occurs in this case, and I imagine that it will result in rather fewer OpenGL calls.
[edit]
Actually, for the sake of expedience, let me simply do just that. Additionally, this was recorded in a relatively minimal scene–while the UI, inventory, etc. are present, I hadn’t loaded an actual level just yet. Behind the UI, only a (now-red) skybox was visible, I believe.
