If I scroll file.txt then - yes - filler lines start to appear in the window displaying /dev/null. Other than that I am unable to get the correct scrolling behaviour you are describing. The incorrect scrolling seems to be strictly related to line 187 in move.c (function update_topline()): 186 #ifdef FEAT_DIFF 187 curwin->w_topfill = 0; 188 #endif as commenting out the line or restoring curwin->w_topfill at the end of update_topline() seems to alleviate the problem. However, I don't suppose that the line is there without a reason (although I haven't observed any undesired side effects after I removed it). Anyway, after such a modification scrolling /dev/null yields a result as follows (note: one more filler line than you are reporting; this seems consistent with scrolling file.txt, though): window 1 window 2 /dev/null file.txt +------------+------------+ |filler |last line | |_ |~ | |~ |~ | |~ |~ | |~ |~ | |~ |~ | +------------+------------+ and upon two more CTRL-Y presses: window 1 window 2 /dev/null file.txt +------------+------------+ |filler |last - 2 | |filler |last - 1 | |filler |last line | |_ |~ | |~ |~ | |~ |~ | +------------+------------+ If I remove "filler" from 'diffopt', my problem disappears. Everything I described happened on a freshly compiled normal version of Vim 7.2.267 invoked as follows: $ vim -u NONE -U NONE -d /dev/null runtime/doc/todo.txt Maybe anyone else observes the correct behaviour and would be willing to investigate which settings make the difference? -- Cheers, Lech --~--~---------~--~----~------------~-------~--~----~ You received this message from the "vim_dev" maillist.
