Ok, looks like I got the answer on stackoverflow:

http://stackoverflow.com/questions/26536362/angularjs-ng-grid-shows-blank-grid-first

It does indeed sound like the resizing problem as switching between dev. tools and back causes resize and also 2 accounts correctly show up right away (but not others).

Adding $(window).trigger('resize'); at the end of the load procedure fixed the problem for me. Now when this guy explained that problem, it seems quite obvious that it was indeed the problem with resizing.

UPDATE. I re-introduced the paging back, all as well now.

Well, thanks to that guy in stackoverflow for the answer!
