Ah thanks, F11 works great, and for F5 i got "Demon thinks your desktop has a resolution of 1366x768, and is currently running a resolution of 1080x720 (1366x768 in fullscreen). The camera is rendering an area defined by (x:0.00 (107.00 in fullscreen, y:0.00, width:1080.00 (1152.00 in fullscreen), height:720.00 (768.00 in fullscreen)):11.25 (12 in fullscreen)". I am running this on Windows 10.
Oh, and have you considered making a discord server?
It looks like Demon is doing the best it can with the resolution you've got, but 720 is as small as it can go on the Y axis. :( If F11 is working happily, my recommendation would be to continue using that; it is unlikely Demon will support window sizes smaller than Nx720 in the near future.
Demon doesn't have its own Discord, but we do have a channel on the roguelikes Discord. :D This link should be a valid invite for it: https://discord.com/invite/HVBmg7
