It seems that the touch is not detected in all frames… Like a lag…
Then I noticed that this problem is not present if the screen is stretched (and it fills the whole screen).
It can be depend by the blend mode? Or by touching screen point with no texture? Can you help me?
Maybe there is an input issue on touch out of first layer texture?
This is a SDL2 bug I think… please help…
Tested with API from 14 to 22.
Edit: I tried to create a texture and I placed it under all texture as a “texture base”.
Now the touch is detected better… but it doesn’t work properly… Why?
Edit2: it seems to be a ghost touch (wrong screen position touch) ex.: i i touch upper/left at random time it seems to touch the bottom/right screen for example…
Something like this happened to me when I used SDL_SetRelativeMouseMode(). Android doesn’t support this feature, so it produces this bug. Not sure if this is the case for you though. I’m struggling to get SDL2 working under Android Studio, so I can’t test it.
