GNOME Bugzilla – Bug 365960
Filtered-out selection looks weird
Last modified: 2006-12-17 05:07:40 UTC
How to reproduce. Put 1,2,3 to A2:A4. Add autofilter to A1. Select C3:E3. Set autofilter to 'Other'-> 'Equel 3' (it will hide rows 2 and 3). You'll see dirty pixels near the right bottom corners of B1 and E1.
Confirmed. It is the selection that got hidden by the filtering. Try shift-left after the above steps, btw.
easy fix.
