I run OpenTTD (x64 version r27875, Windows 7 SP1) in 4K resolution (3840x2160). When i try choose maximum level of "zoom out", I get freeze of game. But forty seconds later game unfreeze with highest level of "zoom out". I immediatly did "zoom in" and again try opened largest view of area. Game freeze again, but successfully unfreeze twenty seconds later. I again did "zoom in" and maximum of "zoom out". It opened twenty seconds later. Again.

So, when game work in 4K (in FullHD all normal), it loading highest "zoom out" level with some time period. While switching between all the others levels of zoom in any direction (out-in, in-out) always instantaneous.

Also, loading of highest view depend on the size of map. Forty-twenty seconds - on 256x256 size. On 4096x4096 loading takes minutes.
This task depends upon

This bug is still in the latest version and it also happens on a windows 10 machine with an 2560 by 1440 monitor with super high specs.
