Subject: [PATCH] scrolling very slow in calc
even on a short spreadsheet scrolling up and down leaves
the first/last row (depending on the direction of scroll)
unchanged until the scrolling stops.
http://people.freedesktop.org/~mst/calc_4.2_scrolling.webm
On larger document there are rendering artifacts during scrolling which go away
after scrolling for me and mstahl, but a bunch of people can show us piles of
horribly broken spreadsheets after scrolling, esp wheel scrolling
