Please keep in mind that not everyone uses a high res screen. 1366x768 is a very popular one, please don't make it too big on those screens. :(

GridUnit * 40 works out to be 720 px high with the default 10pt Noto Sans font, which is enough space to not interfere with the default 36px bottom panel.

But there's no way around the fact that this window greatly benefits from more space. On such a small screen resolution, I would expect people to want to just maximize the window.

Can the thumbnails be smaller instead? That always looks much better on small screens.
Maximize this window is a weird thing, because it's very difficult to see the new wallpaper.

I don't think it makes sense to make the thumbnails smaller. They're already quite small IMO and I often find myself wishing they were bigger!

In the end, a low-resolution screen is always gonna be a low-resolution screen.

Keep in mind that this patch doesn't impose a larger minimum size, just a larger default size.

Which reminds me, I shouldn't have removed the minimum size.
