Performant CollectionView with similar to image gallery layout

[dainius-r]

Hi,

I would like to make MAUI app with image gallery layout page design, like that:

Requirement would be to use GridItemsLayout with Span which automatically makes preferred column count and each grid cell should have same width and height.
To achieve that I'm using: <Border HeightRequest="{Binding Width, Source={RelativeSource Self}}">
Otherwise GridItemsLayout calculate cell height to zero and cells are not visible, or shrinks to minimum defined cell height, e.g:

Using this binding is inefficient and when scrolling you can feel some lag. Is there any way to achieve this requirement without binding value? Maybe overriding CollectionViewHandler you can set somewhere for each computed grid cell height to computed width? Anybody faced similar situation/optimization?
