Comment 4 for bug 1885026

Thanks Daniel for referencing that comment, it's indeed also relevant here.

It seems weird as a whole that the available scaling options appear to depend on common monitor resolutions. As stated there at 3840x2075 (that's 4k minus the VMware window borders) I see the 100/125/175/175/250 selector, at 3480x1859 I don't even get any fractional scaling options at all.

It looks like somebody tried to make it really user friendly by tailoring the experience towards the end user ("nobody wants 300% scaling on a 640x480 screen") and then completely overlooked the windowed VM scenario, or any kind of remote desktop where you also want to be able to set the scaling correctly based on the host machine's resolution.
