have you actually tried e, wayland mode, on a touch screen? i know you guys have ativ laptops with touch screens right? it seems broken. kind of works. kind of doesn't. have you at least tried?
like run as normal - try click on an icon in ibar to launch - mouse cursor doesnt even go there. click and cursor stays where it is... unless i click somewhere on the desktop - sometimes the cursor goes there on the 2nd click. click then drag moves the cursor where it should. i can't click to drag any window around at all. i can click+drag to use a menu but not click, then click again then click again etc.
so basically touch input seems pretty horribly broken. at least on this laptop here next to me..
