This Sunday, Oct 20th at 18:00 (UTC), the KDE Goals champions will be answering your questions live. Post your questions here and I'll make sure they'll answer them.
2 or more Mices at the same time with its own focus. Something that KDE can't handle at all, because those two mice positions are figthing for the cursor
I develop Programs out of scratch using C++, GLFW and glad to communicate with my GPU using OpenGL. Thats my definition for "out of scratch"
I had ideas to create fun little games using multiple mouse inputs. But I was lazy to switch to Gnome because gnome didnt support VRR and I just wanted to push this idea first so it comes to KDE. Its nonsense to create something that will only work on one specifix Desktop Environment.
There is potential for a new Perspective of Game creatioms, but the question is also, can a Program detect different mices? I mean, doesn't matter. Just make the game run 4 seperate Windows and handle the input seperately.
I also slowly start to use Godot and Bevy instead of playing around with C++ and OpenGL
Puuh, I can redo it. But I had a Video 2-3 Years ago where I used a Feet and a Hand at the same time on the table (because one Hand needs to hold the Phone/Cam)
I loved it because its goofy flexing.
Its only possible on X11 Yet afaik because in X11 you can Manipulate XInput and create new Focus Groups to assign your devices there (move them to another group).
This already is used in Both KDE and Gnome Wayland, but only for Tablets (they get theie own Focus group like I can do it with X11 and XInput command tool, its the same but a feature that actually is default). You can also see a difference how Gnome can actually handle both inputs well at the same time, while KDE is a glitching nightmare
