# LVGL builds when nothing is configured: that screen contains a spinner, and an animation cannot

# Everything that affects the rendered pixels is set explicitly, so the expected hash in the test

|
# depends only on the drawing code and the built in font. In particular the background comes from a
|
|
# full screen object rather than from the theme, so adjusting a theme default does not break this.
