Application text not scaling on 3840x2160 display

[kutabare]

Is there a way to make the application text bigger? I've recently upgraded my monitors to a pair of 4k 27" and the application text does not scale as it does with other applications.

Windows is set to 3840x2160 with a text scale of 200%. The desktop and every other application I have tried these settings work well and the screen is displayed as it would at 1920x1080 and 100% scale.

Magic however scales the window title but nothing else making all of the text extremely small and the parameter adjustment controls virtually unusable.

I can revert the display to 1920x1080 as a workaround but it's a PITA having to keep switching resolutions. Has something gone awry with my installation or is 3840x2160 not fully supported?

Thanks.

Have you tried Ctrl + 0?
That will increase text size. (Ctrl + 9 to decrease)

I get a perfectly usable Magic interface on my 4k 17" laptop display with text size at its maximum.

I hadn't and that works, many thanks.
