Object Rendering Issue

[emdeutsch]

I am building a RL bot for Frogger and Space Invader and when I use the RecordVideo Wrapper, as well as when I print the observed frames by the AI, all of the objects on the same row as the AI are not visible for Frogger. Similarly, enemy bullets are never visible in Space Invader. Both of these objects happen to be transparent in human mode, has anyone experienced this and is there an easy work around?

Here are some examples, and as far as I can tell the AI cannot see these objects either. Again, in human mode, it all looks good.

If you are using frameskip>1 then this will cause issues in some environments as some objects will flicker to optimise GPU resources.
You can avoid this through the base environment using frameskip=1, then the RecordVideo wrapper then the AtariPreprocessing wrapper to apply frameskip
