2.8 box selection does not select everything, tiny objects not selected !

Hi there,

I posted it on stackexchange also, anyone knows if this is a bug or some kind of setting !?:

I have a lot of Problems with box selection on objects, there are always not all objects selected !! I don't have any fancy collections or wrong settings in the outliner.

I do have small objects in there (blenderuntis = 1meter), but this is the way a lot of people use it, and was always working fine for me. (with 2.79)

see the file: just (do not zoom in and do) border select and grab x - there are objects missing if zoomed in you can select them, if zoomed out - even less get selected ! blend-exchange.giantcowfilms.com/b/6549/

see stackexchange: blender.stackexchange.com/questions/152453/2-8-box-selection-does-not-select-everything-tiny-objects-not-selected

no one knows, so I wrote a bug report: developer.blender.org/T69802
