Description

Hello! I'm using

• Arch Linux
• plasma-desktop 5.7.5
• libinput 1.5.0
• xf86-input-libinput 0.20.0

While I have "natural" scrolling disabled in systemsettings, that doesn't take effect unless and until I suspend and subsequently resume the laptop. This is reproduced on every boot, and then breaks again whenever I switch to a non-X TTY and back again.

I started recording with evemu, switched to a TTY and back, and then scrolled (thus triggering the reverts-to-natural-scrolling bug) but no events were recorded:
