Equirectangular Projection solar system bodies render bug at edge of screen

[starinastar]

Expected Behaviour

Did: Set Equirectangular Projection. Equatorial Mount on to fix the background stars in place. Sun, Moon, Planets on. Scaled to various multiplication factors. Timelapse on. Expected: all solar system bodies to appear to wraparound back to the right edge when they move to and cross the left edge to the right edge of the screen without visual anomalies.

Actual Behaviour

Got: horizontal lines across the screen whenever any solar system body goes to the edge of the screen.

Steps to reproduce

See "Did" above.

System

• Stellarium version: 23.2
• Operating system: Mac OS "Sonoma" 14.0
• Graphics Card: Apple M1
• Screen type (if applicable): Laptop

Yes, nothing new.

Ok, thanks for the note. I did look for an equivalent bug report but I didn't find one.

I did notice that the Cylindrical projection does not have this issue, but it also does not have full visual coverage in the "wraparound" - meaning, the solar system objects disappear for a moment before reappearing on the other side.

I am trying to recreate this Guy Ottewell poster in a dynamic format: https://www.universalworkshop.com/zodiac-wavy-charts/

This appears to be harder than I expected, I had to revert the fix since it was broken.

@10110111 any news?

As I said above, this is harder than expected, so someone needs to devote more time to fixing this.
