Can see the sun through Earth..

Haven't seen this before. Happens with other planets too, sometimes without the diffraction spikes and just the stars 3D model.

Please upload your se.log file, you can find it in your SpaceEngine /system folder

Can even see the moon and faintly the star through the ringed planet at the launch screen.

I have the same bug, I think it has something to do with "diffraction spikes" not being blocked by some planets

I can't seem to reproduce this bug despite toying with all the diffraction spike settings, at least with Earth as in the original image. What planet is in this image here at the bottom?

I don't remember the specific planet on that screenshot but here is another one I just found. The name of the planet is in the picture

Here is a video as well

Here is another one in the same system and when I turn off the diffraction spikes it disappears

The closest I could get was at the edge of the planet, but not dead through the center as shown here; I wonder what other settings/hardware specifications could be causing this

I don't have the best pc so that could be a thing. GeForce GTX 1060 3GB i5-8500 16GB RAM; I have it set on medium preset

Copied all settings exactly and still nothing, however, I turned on Auto exposure like you have going and now I'm getting results

I was able to find the exposure comp range at which the sun-through-planet disappears. Gonna fiddle around more, but I think this is sufficient to pass on the bug report. Thanks for brainstorming with me!
