Visual bug on shaper realm

https://youtu.be/-8apXiTGYyo

I've gone to the shaper hundreds of times, but this may be the first time I've come across a ramp like this. Climbing up this ramp, I noticed that part of the background had disappeared.

Unfortunately, I forgot to write the /bug command, but this is probably not necessary anymore, since I was able to reproduce this bug again on the video.
