I have searched a lot but couldn’t find an answer to my problem. Lines, isocurves are invisible or slightly visible on all of the viewports. I tried GL tessalation but didin’t work. This happens for whatever file I open.
One thing I caught is if I open raytraced view, then curves are seen on all ports somehow, but as soon as I close raytraced and navigate in the view, they become invisible again. Another one is if make curve pixel thickness higher like 8, I can see the curves, but I still can’t see the edges of surfaces etc.
Below is my systeminfo.
Hope you can find a solution,

Below are same pictures, I highlighted on one to show there are curves there.
