Hi thanks for this git! I'm running docker in Arch Linux on a MBA9,1 2020 with Gnome - Wayland. The resolution setting on my GDE is set to 2560x1600 scaled up to 200% using fractional scaling. When I run the following:

docker pull sickcodes/docker-osx:auto

docker run -it
--device /dev/kvm
-p 50922:10022
-v /tmp/.X11-unix:/tmp/.X11-unix
-e "DISPLAY=${DISPLAY:-:0.0}"
-e GENERATE_UNIQUE=true
-e WIDTH=2560
-e HEIGHT=1600
sickcodes/docker-osx:auto

OSX is huge and does not fit on my screen. If I set my scaling to 100% on GDE the OSX fits but it too small to use. There is no option to change the scaling in System Preferences > Display. Dropping the resolution down makes it fit but it is too blurry to use.

You are using a big display right there, in the QEMU window you can zoom in and out. I'm not sure if you want it bigger or smaller?

Thanks for the quick reply. Zooming out works, and I can make it fit, but I have the same issue with it becoming blurry.

But have you tried reducing the resolution you have selected:

-e WIDTH=2560 
-e HEIGHT=1600

Personally I prefer 1600x900 as it fits on a 1920x1080 screen and I can see everything

Ah I see. You have 200% scaling on the desktop.

Mathematically, it should always be blurry by scaling the outside environment from what I know about the display.
