Subject: erratic scrolling on incomplete lines
Date: Fri, 04 Feb 2005 11:31:56 +0100 [thread overview]
Message-ID: <m2r7jwlioz.fsf@seki.fr> (raw)
Hi,
since a moment I have sometimes an erratic scrolling when pressing PgUp
(that is bounded to scroll-down), and i think i managed to figured it out.
(I am currently on OSX/Aqua but IIRC i have also seen that in X11 in my
GNU/Linux system)
Problem seems to be that the frame is dimensioned such as the last line of
the buffer (except the minibuffer) is truncated vertically. I though it was
not possible as Emacs only sizes by character dimensions increment (i use
the 6x12 font).
Then if, when scrolling the buffer, the cursor is positioning on a line that
would be the last but incomplete if displaying the buffer from the top (at
this moment my cursor is centered vertically) :
1) the next scroll-down step displays the buffer from the top with the cursor
on the last line
2) another scroll-down redisplays the buffer with the cursor centered (point
doesn't move). Any further scroll-down will cycle to the 1)
I hope that my description is clear enough...
Regards.
