QML Mouse area doesn't get unpressed while touching in Android

Recently i have got into some troubles, i asked about it in stackoverflow an some one points me to QTBUG-57603 and QTBUG-58170, i am confused so that i don't know its my bug or Qt's bug

Here is my original post on SO:
I have QML application which has a lot of custom buttons, each button has a mouse area which fills the surrounding rectangle, the button rectangle will be highlighted when the mousearea.pressed became true.

There are some phantom conditions which the mouse area doesn't set pressed to false while the has been gone, when this condition occurs, all other mousearea items will be donky as this, until i switch to another app and back. the source code of the applications is very big thus i can't provide mvce, does somebody faced this problem? this problem only occurs in android, not windows or linux.

because the bug appears randomly i don't know what causing it and can't provide sample code, however my application consist of some flickable items and some buttons (which have mouse area inside it),
