SDL2 + 2 touchscreen -> window ID mismatch

SDL Development
1

I am using SDL2 with 2 touchscreen at the same time, each one with a fullscreen window.
I am facing an issue with the windowID :

  • The 2 windows have the windowID 2 and 3
  • When i touch the window 2 screen, the windowID field of the SDL_MouseButtonEvent struct is 3
  • When i touch the window 3 screen, the windowID field of the SDL_MouseButtonEvent struct is 2

Any clue on that ?

No idea, but you may want to tell if you are using X11, Macosx, Mir,
Wayland, Windows …

Also, I post to remind this patch :
https://bugzilla.libsdl.org/show_bug.cgi?id=2307
On X11, touch event positions are given in pixels whereas on
IOS/Android there are in relative coordinates ( [0; 1] ) .
Would be nice to have all this consistent.

Cheers,
