478	Single-pixel line not redrawn in vterm	Vojtech Horky		"The problem is best described by the attached picture.

The bug was initially reported through [http://lists.modry.cz/cgi-bin/private/helenos-devel/2012-August/008638.html mailing-list], posting excerpt here for quick-reference.

>> When playing tetris 90 deg rotated, a single-pixel line remains drawn
>> in previous position of the falling block. Screenshot is attached. But
>> I am not sure that this is not something related rather to Qemu than
>> to your server.
>
> I am also not sure. But my guess is that it is caused by off-by-one 
> error in damage region calculation inside console server. Another 
> suspect is nearest-neighbor filtering when it is applied on damage
> region coordinates. I will look into it when I will resume working
> on my thesis, which I have to put aside for some time because of
> other commitments. So for now, let's consider it a known issue."	defect	closed	major	0.6.0	helenos/gui/compositor	mainline	fixed
