Rhino 8 - Lines change to gray/faded colour, but curves stay black?

Hi, I am quite new to Rhino 8 but I am having some issues regarding the line colour.
When I draw a straight line the colour changes to gray, like it’s faded.
But if I draw a circle or a line at an angle the colour is black.

The layer of the line is black and the display colour is set to “by layer”.
I definitely didn’t change any settings - as this also comes up when I open a new document.

Has anyone come across this? Any advice would be greatly appreciated!

Hi Marei -

That sounds like a display issue. Please run the Rhino SystemInfo and copy-paste the result here.

I’ve just upgraded to Rhino 8, and I’m getting a similar problem where lines appear to dashed and broken. I’ve uploaded previous jobs where everything was fine, but now they appear differently. The migration from Rhino 7 to Rhino 8 has been terrible, It’s not brought any of my toolbars across, aliases, annotations etc. No a happy bunny.

I’ve pasted my system info below on the of chance someone can help me, but I tried conatcting the team over chat earlier, they asked me to email instead, so I did, and I’ve not had a reply all day.

I’ve had the same issue for some time now, and its really frustrating. (Rhino 8 user)
My laptop doesn’t have the best screen, but there should be a solution to this. AutoCad doesn’t have this problem, and I don’t get why it happens in Rhino. Some lines appear black, and others gray or dashed, all of them supossedly being black by layer.

Any updates on how to solve this??
