Calc is very slow to load and display this document especially while scrolling
quickly even on a fairly fast Intel Core 2 cpu. The file is very small < 50KB so
I'm not sure what the problem is. I reproduced this issue on official 3.0.0.

Tried loading the document and that wasn't slow at all. Scrolling is a bit
slower than usual, maybe due to many different colour attributes used, didn't
investigate yet, but not that slow that I would call it "very slow" (YMMV of
course).

Do you happen to have another computer available to try? Maybe this is graphics
card or driver related.

On my machine it wasn't exceptionally slow though I did see what the user that
filed the Ubuntu bug was complaining about. If I scrolled down a lot at once it
took a noticeable amount of time to redraw on my screen and I have a fairly fast
machine (Core 2 Duo 2GHz). I haven't tested on a slower machine than that but I
would imagine it would be even more pronounced on a slower one.
