Can you use the helper function:

val widgetBackgroundRadiusDpValue =  with(LocalDensity.current){ intValue.toDp() }

LocalDensity isn't available during a glance composition. This is a glance snippet so the code would crash.

if (widgetBackgroundRadiusDpValue < widgetPadding.value) {
return this
}
return this.cornerRadius(Dp(widgetBackgroundRadiusDpValue - widgetPadding.value))
}
