Hiho, im facing serious issues implementing a Horizontal VirtualizingPanel the right way. Virtualization works so far and items are positiones at the right positions but when i scroll though the items, some items start overlapping(for me at Item 671090) and the following Items start creating gaps between each other. This effect increases depending on the horizontal offset. I already tried to locate the Problem watching the itemposition in Debug but its all as it intends to be. Different Implementations found in the internet have the same problem. I tried the VirtualizingTilePanel Implementation provided by Dan Crevier and the StaggeredPanel described in "SAMS WPF Control Development unleashed". Both seem to have the same Problem when i add a lot of items.
Steps to reproduce:
- Add for example 1000000 items for Virtualization.
- Scroll through Data
- Problem starts for me at item 671090(maybe depending on architecture?)
edit: Itemswidth is set to 100.0, Problem occurs at the same index for my colleagues
Any help would be really nice.
Thank you and greetings
