colored markers disappeared from intellij scrollbar

in Intellij Idea on mac, I wanted to remove the extra lint warning yellow marker lines from the scrollbar (still wanted to keep the red & green markers), but upon applying, ALL lines disappeared, so I reenabled all warnings (in editor->inspections) but still nothing on the scrollbar.
How do I get those warnings back?
PS: I should mention the scrollbar is now transparent such that it overlays the code window. It wasn't before so I think resetting that might fix the problem
You can restore to defaults by clicking the cog icon like down below.
It's important to check the Stripe Mark Settings in the Color Scheme. Stripe Marks are responsible for the little colored boxes in the vertical scrollbar of the Editor.

How are these lines in IDE's called?

Do they(pointed as red arrow) even have a name?

how to have colored single border line for rich textbox and buttons in vb.net

For rich textbox in vb.net i want to have single border line. Fixed single and Fixed 3D are having some dimensional effect which i do not want. And i would also like to change the color of the border.
And same thing with the button, for them how to have single line border and specified color.
According to the documentation, the richtextbox doesn't support FixedSingle, so it defaults to Fixed3D. You could put the RTB into a panel and set the RTBs border to none and the panel's border to fixed single.
