Is the scaling algorithm specific to the wayland implementation? I saw a github thread about configuring it in sway but wasn't able to find anything about KWIN. I'd also love a flag to just disable scaling on a per-xwayland-app basis (so I could use the --force-device-scale-factor hack) but couldn't figure out how to do that so if you know something off the top of your head it'd really help out.

Anyway thanks for the tip!
