Opera 23, issue in Google Maps
When I look at that same area with Opera 23 I see the same as your Chrome image, so not a built-in Opera bug. Some setting or an add-on maybe.
Found the problem! With "Hardware Acceleration" set to On Google Maps appears incorrect.
If I disable "Hardware Acceleration" the site is shown correctly!
But is strange! until opera 22 (inclueded) no problem!
I don't know!!....
