Can you run Emacs you built under a debugger? If so, please make an unoptimized build ("configure --no-opt" in the nt/ directory to configure the package before compiling), and please show the values of yb and last_new on line 5021 of dispnew.c, when you press down-arrow on the "123" line in this recipe: > 1. Start Emacs (scroll-conservatively > 0) > 2. Adjust w32 window height (aka EMacs frame) to show (say) 24 rows. > 3. Fill *scratch* with with 32 lines of 'abc' > > Move cursor to top; down-arrow to end of buffer; > Repeat; > > No artifacts > > Add 123 as last line of the buffer. > Move cursor to top, down-arrow and etc. > > Artifact shows up (almost always) at the end of the buffer. > > abc > 123 > | For the record, the values I see are yb = 384 and last_new = 24. Also, since you seem to have problems with cursor display, do you see any change in the artifacts left after scrolling if you play with the value of cursor-type? E.g., try M-: (setq cursor-type 'hbar) RET or even M-: (setq cursor-type nil) RET before you repeat the above recipe.
