Global scale-to-fit?

[Hyz]

Interesting to hear their reasoning behind this decision!

But we're way off from that right now, and even the per-app scale-to-fit often doesn't work when there are popup menus or notifications involved.

That's the biggest issue I had prior to enabling this flag. Hopefully this improved scale-to-fit will fix this. But until the global flag gets removed, I'm keeping it enabled.
