I think I saw something similar posted quite some time ago, before the update. But I encountered a bug with the sun and the glow in the atmosphere, they don't match.

As you can see the white dot is de sundisc while the glow is offset to the right. The lighter spot below it is probably the reflection of the sun on the water.
Yes, this is a known problem. We have not yet attempted to address it as it's not terribly common, but it should be fixed before the final release at the least.

This bug is still present in the latest beta.
I'll fix this for the next update.
