The official White House Android app has a cookie/paywall bypass injector, tracks your GPS every 4.5 minutes, and loads JavaScript from some guy's GitHub Pages.
Unfortunately all of the code blocks are loaded after-the-fact with JS for some asinine reason (highlighting I’d understand… but why the actual text?), so disabling JS also disables all the code snippets on the page.
Not a performance problem. My guess is, they (poorly) emulate native scrolling via JS on mobile. Probably for some progress feature or something.
JS disabled, scrolling works. Though it was only slightly laggy for me.

Definitely a performance problem, no HW acceleration on PC produces the same insanely stuttery scroll.
