I run kali linux on my laptop. I did a total reinstall yesterday, and I don't like the theme that now ships with kali. Both the top bar and bottom bar have a stupid gradient going on. Screenshot:
The top bar used to be solid black, and the bottom bar didn't exist. I would prefer if it was like this but I can't find the settings to change this. Screenshot:
I tried installing a different theme "Oxygenium" (https://cn.pling.com/img//hive/content-pre1/167568-1.png) because I liked the looks of the preview, but it got worse. You can see in the screenshot the top bar is now light grey, and the font is white. Atrocious

Edit: I should mention that I've tried "Activities configuratior" and it does nothing. I should also note that the scrollbars are pretty thin, Ideally I'd like to revert that to normal width as well but it isn't absolutely required.
