Steam and Discord are both X11 apps, so switching to a Wayland session may not help much as they will still use X via XWayland. There may be a way to force Discord to use Wayland as its an Electron app. In general I've found KDE does a great job dealing with fractional scaling with XWayland apps, GNOME not so much. I'm using Fedora's KDE spin.
