I have zero knowledge about the GTK code within Emacs but this problem is related to refreshing the buffer which is not a GTK widget, is it? I also tried something which is even worse: When I split the main window (C-x 2) and move the modeline of the top buffer, everything is flickering: both scrollbars and buffers. It is pretty ugly. --=20 J=E9r=F4me Marant
