In case there are Many ImageButtons inside loop, only the first one can be executed when clicked. Is this bug? If I change it to a normal Button , it works fine.

for(int i=0;   i<10; i++ ) {
  if(ImageButton()) {
     cout << i;
  }
}

First button works, prints 0. Other button does not work.

Maybe this is due to same texturID?
