tdf#136694 - share spelling context across all ScGridWindows.
Reviewed-on: https://gerrit.libreoffice.org/c/core/+/104706
Before the commit, the view can choke up a little shortly after starting the
scroll, but goes back to frequently refreshing.
After the commit, same as in the video: very infrequent refreshing, all the way
to the top.
Looking at the commit, I figured turning off Tools > Automatic Spell Checking
fixes the issue.
Michael, can you please have a look?
Dan, can you confirm that:
- it only happens with kf5 (cairo+xcb)
- turning Automatic Spell Checking makes it smoother
