I have strange behaviour of my application. I display nine buttons( four different style - App.xaml ) in window but sometimes one or two buttons disappear. It isn't regular. Sometimes button contain only one part(small rectangle or content). Buttons are similar but a bit different. That's why i have to display four different buttons style. Any suggestions how to solve this problem?
