The problem still appears after doing that. I just noticed that C-l also cleans up the display (perhaps not that surprising). I just found a simpler recipe to reproduce the problem: * Start emacs -Q * Split the window in two: C-x 2 * Unsplit it: C-x 1 The text in the *scratch* buffer is repeated after where the line should end: · https://koldfront.dk/misc/gnu-emacs/redisplay-simple.png and it stays that way until I do something, like editing the buffer or pressing C-l, for instance. Both with and without double buffering. Best regards, Adam -- "This Interweb thing, it might just catch on, I'm Adam Sjøgren telling you." asjo@koldfront.dk
