System Information
Operating system: Windows 10 / Ubuntu 20.04
Graphics card: GTX 1080 / RTX 3080

Blender Version
Broken: 2d9d08677e a2d59b2dac
Broken: all versions >= 2.8
Worked: 2.79

Short description of error
Viewport display of Dupli-Collections is inconsistant.
Digging deeper into it, it looks to be when there are different draw types on the same dupli-collection

Exact steps for others to reproduce the error

Open attached blend file
select the empties in the middle of the screen which do not look like they have anything attached
notice how they randomly appear / disappear upon selection.
note that one of instancer is set to Textured draw type, the other to Wire, if all are set to Wire the issue is gone

This has happened in quite a few of our production scenes.bug.blend

NOTE: Might boil down to be the same as #101822 (Collection instance set to Display As Wire doesn't show in Solid mode when not selected) or #86732 (Instanced wire objects are hidden in solid mode instead wire appearance)

New file created by one of our artists to reproduce it easier

Open attached blend file
Mouse over the outliner
Hold down the down arrow / up arrow when it hits the bottom
Notice how the collections appear / disappear out of thin air, but in the order of the collection

@brecht might know more since he did ca06b84900 otherwise @fclem should know.
NOTE: Might boil down to be the same as #101822 (Collection instance set to Display As Wire doesn't show in Solid mode when not selected) or #86732 (Instanced wire objects are hidden in solid mode instead wire appearance)
