I have created a widget that I like, but every few days the elements get randomly moved around the screen and the only way to get the old placement back is to manually rearrange them.
This has happened 5-7 times in the last month and I've tried a number of fixes (restoring from a save point, restarting the phone, etc), but none of these work.
I have double checked that the settings were correct. The orientation and size options had been set to what you suggested, but the issue still persists.
