Calamares should work better with smaller screens.
I said on the devel channel yesterday(?) that I think it's too late for release, but seeing as it's default in Virtualbox, it makes it much more urgent in my eyes. If we want to retest everything, Adam did say this on Thursday...
[20:53] <infinity> tsimonq2: Ultimately, for packages only you seed, you have final say anyway (up to a point). If you want to upload something and respin and retest all your crap 6 hours before release, be my guest. [20:53] <infinity> tsimonq2: If you want to do it an hour before release, you might have missed your window. :P
That being said, I want @guiverc's input on this, because he's the AWESOME (seriously!) tester who has been plowing through the testcases.
Well here's a weird thing: I haven't had any problem with 19.04 in VirtualBox booting to a reasonable size, i.e. not a little 800x600 screen. Whether or not that's true, I don't think we need to make it so urgent, especially when the release notes link to a bug that provides a simple workaround: go full screen.
