Sorry, the information I mean to convey is that your problem is probably
an incorrect DPI info (presumably one influenced by the display driver
since changing the driver affects the result).
E.g. you may want to compare the physical screen size that `xrandr`
announces with the real size of your monitor (and also comparing the
size you get with nouveau and the one you get with nvidia).
