How to remove most highlights from scrollbar in JetBrains IDEA?

I am exploring code with a lot of problems and my scrollbar is looking like

I don't see any sense of flooding entire scrollbar with yellow. Also it prevents me to see something important like scrollbar knob. Can I disable scrollbar notifications only? I would like to remain problems highlighted in code.

Solution

Settings (Preferences on macOS) | Editor | Color Scheme | General | Errors and Warnings, disable the Error stripe mark for all the items.
