#1
You can barely see the outline of the sun - it doesn't have any shape. It just looks like a part of skybox that is slightly more red or slightly more blue.

After some very quick testing i can see that with bloom turned on there is no issue for me (GTX760)

Witch leads me to believe this may be an issue with drivers/GPU/Your end. But i would like to investigate this more as you clearly are having an issue. Please provide steps to reproduce this effect and any other info that might help me investigate this for you.

#2.1
Thank you for providing more info I indeed have heard of amd having issues in the past with this. If you can test this to make sure it is a driver issue by updating to beta driver that would be great. As for now this bug seems to be AMD only as such Bug has been formally validated and is indeed there. as i have an GTX card i cannot test amd side.
But other then that i will be more then willing to hand it off to you SmilingDemon Good bye :)

Just did a quick test on AMD HD 5450 GPU

maybe AMD related then ? (red Circle is the sun )

#3.1
2nd Test
AMD R9 280X with Driver Version 14.501.1003-141120a-177998C
Looks Good to me (again red circle is the Sun)

Aceface are you able to provide your Settings.cfg and what GPU and Driver are you using ?

#4
the white suns are fine, its just the blue and red ones that i have a problem with

#5
More Testing. On old HD 5450 GPU with older Driver 14.10.1006-140417a-171099C
First without Procedural Background (red circle is Sun as usual)

Then only procedural Background on with 2048 setting

it was the only setting in your settings.cfg that had any effect for me.

#6
two problems here
1- the nearly invisible sun from #1 #3 and #5, maybe caused by the procedural background being off
2- the effect from #2 (have seen that with red suns too - starfield is visible behind this dfifuse sun - happens with proc background on too
3- i guess some kind of shader magic problem ??
