The tweak I found was essentially learning a new way to resize windows. Hold ALT and right-click-drag from anywhere inside the windows at the lower right corner and it'll grab the window and resize it as you move the mouse.

I know it's not a fix, and it is still cumbersome if all you have at the moment is a laptop trackpad. But it beats having to update your destkop environment's chrome and all that jazz. I find XFCE's window chrome pleasing and minimal, the only issue is exactly that, you only have 1px of hot area at the borders.
