Are you saying that completely redisplaying the window (e.g., with "C-x 0" followed by "C-x b THAT-BUFFER RET") makes the display correct again? I guess not, in which case this is not about _cursor_ positioning, but rather about _point_ positioning. Right? Anyway, since Joe complicated the recipe with going full-screen (which makes everything dependent on the monitor dimensions), I would ask you two to answer the following questions: - Can the issue be reproduced without enlarging the font? - Does the issue happen only in continuation lines? If so, does it happen as soon as the line is continued, or do you have to have several continuation lines? - Stefan, did you see it on the emacs-24 branch or on the trunk (or both)? - Is it important what text to type, or will any text do? (I cannot reproduce this no matter what I do. I'm tempted to say it's X-specific, but I fail to see how could it be.)
