What did you do?
Built a production on Gleb

What happened?
graphic bug that occurred with the biochamber when selecting a recipe with liquid input/output, a shadow appears on the side where there is a liquid interface. The shadow changes if the machine is rotating.
In the screenshot I indicated the shadow that appears, the direction of the arrow from the machine from which it comes.

Does it happen always, once, or sometimes?
At the moment, once, I was not able to reproduce it on other PCs / in a new world, and when I returned to the world where the bug occurred, it was gone, I'm not sure if I should even make this post(always, read next message)

I was able to get it again, I don't know yet what the reason is, but if you save the world in this state and transfer it to another PC, the bug remains in place.
The most interesting thing is that the bug only appears if it is already a "broken" machine or copied via Ctrl+c/Q or blueprint

Blueprint itself
Copy blueprint

EDIT:
Now when I rebuild the base on Gleb for the 3rd time I realized what I did to make the bug appear, it is enough to take the biochamber and use one of the flip keys (H/V) so that the interfaces are on the other side, or swapped. I was able to repeat the bug on another PC under Windows (log in attachments).
