Multi-touch bug Android (MIUI)

[azoyan]

Hi all! I have a problem.
If you touch and hold your finger on the screen. When the number of fingers is three, the touchrelease event will be called and the release count will be equal of two.
Code for test, main.lua:

Code: Select all

touchPresses  = 0
touchReleases = 0

function love.touchpressed(id, x, y, dx, dy, pressure)
  touchPresses = touchPresses + 1
end

function love.touchreleased(id, x, y, dx, dy, pressure)
  touchReleases = touchReleases + 1
end

function love.draw()
  love.graphics.print("PRESSED: " .. touchPresses .. " RELEASED: " .. touchReleases, 10, 300)
end

I record video. Touch-pressings areas is shown by the recording application. https://youtu.be/9XVIXXwzRc8?t=1s

It looks like it's a problem with that phone's screenshot mode: http://en.miui.com/thread-532593-1-1.html

Maybe it is needed to report new issue in love2d?
Because, in other applications (no love2d) this bug is disappear: 3 touchpresses processed normal with enabled '3-finger slide screenshot feature'.

As far as I know multitouch works fine with love on other Android phones. Maybe most other apps use multitouch in a manner that doesn't trigger the issue in that phone's software (for example if the other apps use high level OS gesture detection APIs instead of the lower level touch tracking that love exposes).

Does multitouch work fine for you in other non-love games on that phone?

Quotha! Yea! In other games third touches is doesn't work too. In applications it's processing this correctly
