You will not find many other widgets similar to Bubble Clouds, which can change their appearance as bubbles are added or moved around or the widget size is changed. But to be able to do this, Bubble Cloud Widgets have to “know” the exact dimensions of the space they are given.
By Android standard, launchers should notify widgets of their exact dimensions.
However many launchers don’t do this correctly. If Bubble Cloud gets the drawing area wrong, the bubbles will be distorted, overlap etc.
