In recent tests that I’ve seen, KDE has better touchscreen and multitouch support. It’s long been thought that Gnome was gunning for the touchscreen market, but they got overtaken, because their release cycle is slower.
But I use a Wacom tablet with Gnome, and I agree that the pressure support is great.



Which DE? CachyOS has several options. The “Open With” menu option works great for me, but I’m running Gnome on CachyOS.
Flatpak doesn’t always work correctly, because you may need to explicitly allow the app container to access certain system services and paths. You can usually do this easily in a program like Flatseal. Most apps should work correctly, however.
