@herag I use it with unit scaling. My fvwmrc has normal window commands (move resize iconify close etc.) in the root menu so you don't have to touch the controls precisely if you don't want to. On the menus you can just "roll" your thumb and the different selections get highlighted.
I also make XVKBD sticky and without a title bar like the iconbox.
Most X11 things really function very well with unit scaling. The only thing you really miss is mouse buttons 2/3 (so no quick selection buffer pasting etc.)
