Example of print preview column repetition bug in calc after using tilt wheel

While viewing a zoomed in view of the print preview, I can use my mouse tilt wheel to scroll left or right. The view does shift fine, but at the edges where new text should enter into the screen, the old text is still present. This gives a somewhat 'striped' appearance with repeated text running alongside each other down the screen.

I have included a screenshot to help. Notice the green column and the £50 column are repeated. This is after using the tilt wheel to scroll left.

This effect remains in force until I move the preview up or down (with the mouse wheel), use the cursor keys to scroll in any direction, or simply move the mouse cursor at all.

For reference, the mouse in question is an MS-Intellimouse Explorer 4, the issue is only present in Calc, and only on the print preview. It does not occur in the main screen, or on Writer preview.

Not sure it'll help for what seems to be only a screen refreshing issue, but here you go.
