On this Linux laptop, touch screen taps on the laptop screen cause which=0 mouse down events, instead of which=SDL_TOUCH_MOUSEID. This has the potential to wreck havoc on touch input handling for any application that does its own touch processing (which I wanted to do), since this effectively makes it hard (impossible?) to tell apart regular mouse clicks and touch taps.

Hardware: Thinkpad Yoga 260
OS: GNU/Linux Fedora 28
Desktop: GNOME 3.28.2 (Xorg Session, not the default Wayland session)

I investigated this some more, and I'm not getting touch events AT ALL - every touch is just a which:0, button:1 mouse down. This is with SDL2 as provided by Fedora. Is this potentially some compilation issue, with some extension required for proper touch processing not compiled in?

I now filed a Fedora bug report here, since I don't know if this potentially a packaging issue: https://bugzilla.redhat.com/show_bug.cgi?id=1634291

I haven't seen this for a while, so maybe it was fixed on Fedora's side
