It seemed to me that it happens on certain posts. It crashed on me when I scrolled past one, and consistently would. It also happened again later on start, but that was gone when enough new posts were there.

I can’t pinpoint the type of post though, or the individual posts.

If you like it old-skool-style, wizordum just got released in early access. There’s a playable demo as well

Looks like colemak
