Actual Behavior
Running the game on PC:
Everything acts normal.
Running the game on the emulator (mobile also works)
Notice how no game processed is fired despite being on top of the button. The mouse location is also different. I suspect that on mobile, button clicks are registered before the mouse location is updated, causing the system to think the mouse isn’t on the button but on another part of the screen.
In this video I’ve also included where the mouse location is directly after the MouseButton1Down event is fired (in green):
Notice how the mouse location is at the previous click.
