Bug? Strange Whole Map View

[severe geode]

Something strange displayed on my Mac.
Restart the game can’t fix it.

Device: 2020 MacBook Air Intel i5 version with the latest MacOS

Something similar happened to me but it was a large strike of diagonal but straight water

Your system is macOS too?

[deft atlas]

No i have ColorOS, im oppo android

[severe geode]

does this also show in other apps?

[severe geode]

This is definitely the App’s problem, the same map is normal on iOS version but it looks strange like this on macOS version

Could be GPU imprecision issue. Also, those previews don't update unless you enter and save the city.

Those strange things only come to existence after entering and saving the city, some blocks in the image do not have those strange things because I never entered them
