Here’s a link to a basic screen with 1 column and one button with an image as background.
When I run the app on android simulator (and also on a real device) the button flashes/flickers for a few seconds.

I’m not seeing any flickering on an iPhone in Thunkable Live. But I have heard others mention that screens seem to load more than once. And I had a Thunkable staff member confirm that one of my projects seemed to load twice when I used a “when screen opens” blocks. I haven’t duplicated the problem with other projects yet.
When I download the APK and install it on a real device it flickers. On my actual app, I had to overcome this by adding a loading screen which really sucks
