(In reply to Molly Howell (she/her) [:mhowell] from comment #4) > 2, KDE does not seem to believe that a touchscreen is even present, there's nothing about one in its control panel. I suspect that Steam input is emulating a mouse and funneling everything (the touchscreen, as well as its own touchpads and controller inputs) through that emulation. Indeed Gecko doesn't report touchscreen support. https://patrickhlauke.github.io/touch/pointer-hover-any-pointer-any-hover/ should report `any-pointer: coarse` if it thinks there's touchscreen. `navigator.maxTouchPoints` is also 0.

(But Gecko does get touch events.)
