Wow it’s been 2hours 😶. There now is a lot of things who have change ! There now a full Display Properties app (1st screenshot). And when you select a wallpaper there is a preview who fit perfectly into the screen and there is the ability to change the real background (2st screen shot) I’ve also redraw every wallpaper (for the most is just 32x32, 128x128, 64x64 or 16x16 repeated through the whole screen)
