1px gap between maximized windows on left and right dual screen monitors.

[Ezra Sharp]

See screenshot, I made my background a solid bright purple colour so you can see the gap. If full screen video is played it covers the gap perfectly, all non-fullscreen apps reveal the gap when full maximized.

The gap is not visible above windows, as in apps cover it with no issues when not maximised.

I can confirm this. It's not a gala bug though, but a mutter one.

I am unable to reproduce this in 13.04

[Calum (calum.)]

I got around this bug by giving my left monitor (the one without the gap) an underscan of 1 in the NVIDIA X Server Settings.
