SF Mono is stretched horizontally on external displays

[nighthawk469]

SF Mono looks good in ghostty on internal retina display and matches iTerm and Terminal

On external display SF Mono is stretched. iTerm and Terminal render SF Mono properly.

Default JetBrainsMono Nerd Font doesn't have this problem.

font-thicken on or off does not change the problem.

The problem is more noticeable if you download internal/external image and switch between the pics in finder with quicklook

Thanks. This is a dupe of a myriad of DPI-related issues on macOS. We're looking into them now.
