Is it possible to make the lines thinner?

Enable？
--disable-dwm-composition

Thanks, but not working. That is for disabling tab previews.
I want a lite border, like in Chromium.
In other forks works disabling "Use hardware acceleration when available" but it is missing in Catsxp.

Sorry, it's not missing. I mean it's disabled, but not working.
