Issues, Workarounds & Localization

From 2 days ago, I'm seeing strange green and yellow dots, in the background of the stars.

They aren't always there... at this moment, for example, I can't see these dots, but 2 different days, at the same hour, it appears again.

They're visible from different wormholes.

I've tried reconnecting, but the dots are still there.
I also tried modifying my graphical options, but when I set full graphics, I can see these dots much better, like other stars.
If I set graphics to minimum, they're difuminated, but still in the same place and perfectly visible.


Also, my corp-mates can't see these dots. It's a bug, corruption on my files...?
