[Question] Disappearing shapes

See original GitHub issue

Hi. I’m using WPF component with a shapefile source. After zooming in some shapes(countries) are disappearing. After zooming out the countries reappear. See attached GIF: dissapearing-countries

This happens in my clean project based on shapefile sample with version 3.0.1 Mapsui from Nuget. Building Nuget packages from master branch and using them did not help. I have also tried to reproduce the issue directly in the Mapsui repository - shapefile sample and I cannot reproduce it. The only difference is that in my project I also have mouse move event handler which I omitted in the reproduction since IMapControl does not expose MouseMove event.

Do you have any idea what could cause that? Thank you in advance.

After investigating a bit, this behaviour is probably caused by the window layout. After creating a layout from the ground up instead of modifying the layout in sample project, everything works as expected. I consider this issue resolved. I will keep it open for a few days if someone else would have anything to say.
