PG 5.0 - High Contrast Theme adding thick borders around panels

This may not be a bug but High Contrast theme adds large thick borders around the panels which gives less room within the interface. I like the High Contrast look but I can’t use it because of these borders that are created.

I use the Dark gray (default) Theme but if High Contrast had the same interface look without the borders I would use that as my default. Right now this is not usable for me.
