XenBad

Windows 7, 8, 8.1, 10 -> Fedora Workstation -> Fedora Silverblue -> NixOS

I don’t use the Flatpak, but for me the rpc doesn’t seem to work for Steam games, it seems to work for everything else that supports it though.

They’re great on certain desktops, like Fedora’s Atomic Desktops, but you usually have to work around Flatpak specific issues. On NixOS there doesn’t seem to be a declarative way to install them.

Have you tried Open Tablet Driver (if your tablet is supported)? I use it on Wayland and it works perfectly for me, but I’m not an artist and I only use it to play osu!.
