With 480x800 display size and height proportion of "1.0/3.0", the buttons of the first line are shifted/overwritten: "iopwertyu" Increasing size of area by setting height proportion to "1.0/2.5" works around this issue.

I tested fbp on postmarketos with a device having 480x800 screen size. It fails with an integer overflow because the status message "Statusfile unconfigured for device!" didn't fit on the screen. The fault doesn't occur if length of message is reduced.
