Yosemite Visor Fade only Fades Container

I finally got around to getting a new computer and upgraded to Yosemite. I set the visor to fade and not slide, but noticed that it only fades the tab container. The tabs themselves just pop in and pop off. It’s very jarring.

I’m running TotalFinder 1.6.17 on Yosemite 10.10.2.
