Huh! I can look into it sometime, but I"m so tired haha. Thanks for your care. I hope you enjoy the mod.
There are a number of entities such as inserters and other things which are constructed out of geometry that is animated rather than just a sprite, so they will always look strange a little, but what you describe may be addressable, so thanks. Though I don't feel super urgent to push right now, maybe later today or tomorrow.
Thank you Yodo9001, it is kind of you to care for my silly mod. For me I love it, and I'm glad you find it also fun :)
