I'm not that familiar with Xinerama, but the screen is always a
rectangular, so there is some dead space the window manager has to be
aware of [1]. Seems to me like dwm isn't.
But anyhow is there a reason why dwm still uses Xinerama instead of
XRandR. [1] states that it's deprecated in favor of XRandR.
