I am using Chrome and I have Windows 10, I7 5500U, 2.4 ghz, 64 bit, 8gig, Intel HD graphics. I am experiencing the same thing as ddevil.....All cities are zoomed in when I visit them. I have to unzoom each time. It is annoying because it is hard on the eyes to keep being zoomed in and then having to zoom out.
Additionally, as I leave a city and have hit the map button and it is pausing to go back to the map, the city I am visiting loses all color and is in black and white. As someone who gets awful migraines, this is kind of a big deal to me because the city gets brighter when that happens and the flash hurts my head. So, I am just shutting my eyes each time. But these are hopefully just tiny tweaks.
One thing that isn't so tiny, is that there is now a long pause when I click on a city, the city goes black for a sec, then white, then it loads. But I haven't noticed it happening every time.
Edit: as I kept testing, I got a shockwave crash.
2nd edit: If I turn off hardware acceleration, I don't have to worry about the black and white issue, but I still have the constantly zoomed in issue.
3rd edit: If I go from town to town through my fellowship, I don't have the black and white issue. This only happens when I go from a town to the world map. So, if the zoom issue could be fixed, I would happily use this new feature!
