Subject: 24.2; Text flickering moving cursor with box around text enabled
Date: Tue, 27 Nov 2012 11:42:24 +0100

*** E-Mail body has been placed on clipboard, please paste it here! ***

The problem occurs when I customize hl-line enabling box around text
to make evident the current line.
The box around text (also 1 pixel) changes the inside text position
thus producing a vertical and horizontal flickering when I move the cursor.
Setting a box of width -1 (a negative number) stops the vertical
flickering but still remains the horizontal one.
