Platform

macOS

Describe the bug

I compiled the latest version of the engine on macOS Sonoma 14.6 and the resolution selection is obviously does not correspond to the reality. As you can see from the below screenshot 800x600 resolution is not as it should be:

Most of users will immediately try the highest resolution which leads to this:

You could imagine the frustration of players seeing this :)

I am using MacBook Air M3 for tests.

Well, it's as it should be... sort of. On macOS and iOS, there are "physical resolution" and "logical resolution". For instance, iPhone 15 Pro Max has physical screen resolution of 1290x2796, while it's logical screen resolution is just 430x932. So when you are setting the window size, you are setting it in terms of "logical pixels", not "physical pixels", while the list of available resolutions is probably taken from the "physical" display parameters.
