[Solved][0.17.64] MacOS display scaling bug

[lacika2000]

Hi dev team,

I have found a MacOS screen scaling bug. I am using a 4K display (Samsung U28E590) with my Mac. When I am running in default scaling mode with this monitor (when I click from default to scaled it says "Looks like 1920x1080" on U28E590, see screen cap), the Factorio starts up in 1920x1080 resolution, despite the native 4K res available and the OS using it. The game is still pixelated (ugly) as needs to be scaled up by the display to 4K instead of the game using the 4K res. Factorio uses 100% scaling for its interface. See factorio-scaled default.log for details.

If I change the display settings to "More space" ("Looks like 3840x2160"), then Factorio starts up with the native 4K resolution of the display, applies its own scaling to the interface (200%) and everything is in its glorious 4K res state in the game. See factorio-native res.log for details.

Obviously, as a temporary solution, I will change the display settings for playing Factorio each time and change it back once finished playing, but under Windows the OS scaling is not an issue at all, so I guess this should be possible for MacOS as well.

Maybe there is a way to adjust which screen res Factorio picks up from the OS (native screen res vs 'what it looks like' after OS scaling applied)?

Your help is appreciated, as always.

Additional information that might help with this bug: "Render in native screen resolution" option in Graphics does not change anything in the game, changing it (setting it on or off) does not introduce a game restart...

Hello, did you install fresh 0.17 or did you update to 0.17 from 0.16?

Hi Posila! Can't recall, to be honest, but I suspect I have upgraded, as the machine is from last year October... Should I try a fresh install?

Should I try a fresh install?

if that's not too much trouble, can you try the fresh install?

I have removed the program, downloaded the latest experimental, installed it and it seems to resolve the resolution problem. Now the game recognizes the native 4K resolution of the display and also applies the right scaling to the interface, so no pixelated screen for me anymore, everything looks great.

Although I don't understand why or how this is the solution, thank you for helping!!
