Seriously, how is it that this has been a problem since beta? Fix the planet graphics so none of them use models that are too bright to look at. It's one thing if the atmosphere or whatever is a bit reflective and bright, but it's another when it looks like you're flying into a sun and can't even see your ship against the star-bright planet.
What makes it worse is even the less blinding bright planets are reflecting more light than the local star is putting out. Ouch!
It's not about trying to find workarounds. It's about what appears to be a bug in the way the missions (primarily exploration cluster missions) choose the planet graphics. It's always been like this and it doesn't need to be. If there's a planet you need to fly toward, make sure it can't grab graphics for a star, or a gas giant either, for that matter.
Worrying about minor window lighting mistakes on a starship is a lot more nit-picky than this, so why can't it just get done?
