Fullscreen is not "full screen" on raspberry PI

[WolfgangFahl]

If there is a taskbar (on top) then there is room on the bottom of the screen:

https://raspberrypi.stackexchange.com/questions/72118/set-display-resolution-for-official-7-touchscreen-display

shows how to change the screen resolution

root@pito:/boot# fbset -s

mode "800x480"
    geometry 800 480 800 480 32
    timings 0 0 0 0 0 0 0
    rgba 8/16,8/8,8/0,8/24
endmode

with 1024 x 614 resolution the fullscreen view seems to be o.k.

root@pito:/boot# grep frame config.txt 
framebuffer_width=1024
framebuffer_height=614
