I have a button with an image of size 64x64 and blank text (property text is empty). Propoerty height and width are both set to “Automatic”. The imageformat is PNG.
In the designer the button is shown as a square, as expected. The installed app however shows a deformed button (see screenshots).
My device is a Redmi 5 Plus, Android version 8.1.0.
A similar project compiled with AI2 shows the correct squared button.
