A frame move should never resize the frame. Apparently the size hints are working here. Does it resize when you set `frame-resize-pixelwise' permanently to nil too? As an aside: IIRC trusting the values reported by xwininfo is just like trusting any values reported by Emacs - they are partially based on what is written into the size hints. > Yes, I do.

And all other sizes that are not an integral multiple of the default character size, I presume. But when you split a window via C-x 2 and mouse-drag the mode line of the upper window by very small (pixel) increments do you see any corruption too? > After getting the mode-line right by refreshing the frame, only > scrolling can possibly corrupt the mode-line again. > >> Do you have to scroll the window in order to show the corruption? > > If the frame was refreshed, yes.

How does scrolling an upper window in a split frame work in this case? martin
