We need to determine if this is a problem with how we put the tiles togther to create an single image or if it is something else. For example, there is a linux bug about drawWindow showing white (or black) lines.

Is this a duplicate of bug 556046?

Comment 3

[Vivien Nicolas (:vingtetun) (:21) - (NOT reading bugmails, needinfo? please)]

imo, Matt is right and this is a duplicate of 556046. This happen when we draw from the tiles instead of calling drawWindow (for performances reasons - this avoid to re-ask the layout and how should it be draw).

What is interesting is that this is more viewable with iframes.
