How to disable HiDpi on macOS and quartz backend?

Hi,

Is it possible to disable GTK/GDK hidpi mode with pygtk3 - on macOS/Quartz backend?

I’ve tried to set various environment variables such as GDK_DPI_SCALE and GDK_SCALE seem to be ineffictive, while hints such as in HiDpi howto

gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "[{'Gdk/WindowScalingFactor', <2>}]"

cannot be used on macOS/Quartz.

I failed to find a way to disable hidpi with pygtk / macos / quartz environment.

Thanks,

Emmanuel.

It does not appear to be possible on the gtk side. The gdk quartz backend uses the NSWindow backingScaleFactor property.

GDK_SCALE doesn’t work on Wayland either, apparently.

Ok. It would not be required for a regular use, but it could have been useful for troubleshooting purpose. Thanks for your reply.
