OpenOffice Calc slow on F11?

[Alan Evans <ame fedora gmail com>]

Is it just me? Since the update to F11, OpenOffice Calc is *slow*. Really slow.

Like, go to an empty cell and type a number and hit enter then several
seconds pass before the screen redraws and the number appears in the
cell.

It was never a speed demon, but before F11, entering data wasn't an
opportunity to switch tasks while the spreadsheet catches up.
