Flickering car, wagon

DESCRIPTION:

when I see my city closer there're little wagons or cars

but sometime, every wagon, car, little people is flickering

It's quite annoying and I hope developer fix this problem

ATTACHMENTS:

flickering issue is hard to prove with picture but every game I have played has this problem and I heard other has this issue

HOW TO REPEAT:

It's Ok when I reload the game but when I end my turn It happens again

air unit issue

DESCRIPTION: some picture would be enough to understand this problem. 

ATTACHMENTS:

when I order one air unit to bomb enemy city, two air unit model are overlapping

I think It's also graphic issue, not actually bombing two time

multirole fighter is Ok, I didn't test biplane or america UU 

you guys should check them

HOW TO REPEAT:

just bombing enemy unit, city with your air unit
