I should add, it seems to only happen when I'm already connected via wireguard.

Comment 2 David Edmundson 2020-10-20 22:04:02 UTC

From the trace it happens during some gesture (swipe/pan on a trackpad etc) does that seem familiar of anything you might have set differently?

Well never mind I guess, fired up my pc today and I'm unable to replicate the "bug" anymore, I don't have any form of trackpad connected to my desktop although KDE does recognize some "Game Controller" that's supposedly part of my keyboard. Not sure what it means.
