Short description of error
When I try to select vertices or faces or edges from long distances or in tiny meshes the geometry behind them is also selected. But I don't want that, I want to select only the geometry I can see. The problem is pronounced more when I try to work with hexahedral meshes.
Exact steps for others to reproduce the error
Just try to boxselect from far distances, in the blend file I attached. You can see that you can select the geometry behind the geometry you can see.
