In Little King's Story, all the sprites (flowers and bushes) are missing their alpha channel as seen in the included screenshot. However, enabling per-pixel lighting and per-pixel depth seems to fix this, but per-pixel depth seems to cause bad stuttering issues. I also encountered a bug where the game starts to play every sound effect one after the other (seems to stop when the music changes, really annoying none the less).
