The problem was indeed with input, after I disabled all input devices except touchscreen
that problem disappeared. The most important bit is disabling
all keyboard devices (both virtio keyboard and hw keys such as volume up/down, etc.) and
a mouse.

After that next problem was met, it seems that crosswalk uses GL_ARB_texture_rectangle
extension without checking for it, our qemu currently supports only GL_OES_texture_npot,
this is required by Tizen according to this - https://wiki.tizen.org/wiki/Porting_Guide/Graphics_and_UI
GL_ARB_texture_rectangle is not required, so it wasn't implemented. I guess we'll have to implement it
just for xwalk. Anyway, no big deal, this isn't too much work.

But just in case, is there any way to tell crosswalk not to use it or at least make crosswalk check for
extensions before use ?
