I don't understand what "moving the frame" means. Does "left side" mean VGA1 and "right side" LVDS1? What evidence do you have that the window manager "resizes" the frame when you move it? > So, my original report was based on a > spurious intervention of the window manager.

And you get the corrupted mode line when you do "not move" the frame as well? Elsewhere you asked to "please, provide a way to make Emacs optionally redraw the mode-line after any scroll operation". How does scrolling enter here? Do you have to scroll the window in order to show the corruption? Maybe you could give us a step-by-step scenario of what you do to the show the corruption, how to remove it afterwards, and how to show it again after it was temporarily removed. I don't have the slightest idea why the mode line would _not_ be redrawn after scrolling but maybe there's some optimization here. In any case with emacs -Q moving the window's point from one line to another should redraw the mode line to show the new line number. BTW, suppose you evaluate (set-frame-parameter nil 'bottom-divider-width 8) Does that impact the appearance of the bug in any way? martin
