Graphics engine bug, do you think Roblox will fix that?

Hello I’m DarkBegin, I’m a small builder and I try to make mazes with mesh walls. When I’m testing my game on my PC Gamer, it works very well (no problem)! When I’m testing on my Mac Book Air, it crashes I guess, when I’m playing on phone, I can play with a really weird graphic engine hurting my eyes sometimes, here some screenshots and a video.


In this video, we can see when I turn my camera in one angle, it works well, but in another angle it works bad!

So I tried to replace my trees by single images, and I removed 30% of triangles of my meshes.
It’s really important for me this game works well for basic computers. All my walls have the same mesh. Why Roblox does consider itself to be different from each other meshes?
Thank you, sorry for my grammar.
