A small gap appears between two or more objects that are actually touching when you zoom out - but when you zoom in it disappears - very annoying.

Are the gaps visible at 100%?

What is the source of the tiles? Are they abutting layers? Smart Objects? Rasterized PDF/AI content?

gaps are not visible at 100% - they are not smart objects or rasterized pdf - regular layers - would happen if i created shapes - happends to any content that I line up next to each other and then zoom out

There was a similar problem a few years ago with art imported from Illustrator. The thin white line would be visible at 100% and would be visible in printed output. Since you don't see the line at 100%, I suspect it is unrelated to that issue.

This is because PS renders all layers seperately and if you zoom out then all pixel-perfect layers are interpreted as halfpixel on edges. You can see it with rectangle shapes also
50% zoom: 
66,66% zoom
(align edges must be turn off)

Workaround would be wrap all into smartobject, work inside smart object hit ctrl+s and switch to parent document for preview. Smart object has merged bitmap which is taken from 100% zoom inside child document. And because is merged then it's rendered as single layer.
