I can confirm this bug. If you look carefully to the top of the picture I posted, you will see a blue bar between menu bar of Firefox and the top panel of XFCE. That blue bar is the desktop, in fact.
The same happens in CyrusCT screenshot, but he has the XFCE panel at right and the gap on the top (he has a black desktop background). I've tested changing the theme and the windows decorations to no avail. :( It seems to be related to the way XFCE paints the window decorations. ** Attachment added: "Maximus gap on XFCE" https://bugs.launchpad.net/ubuntu/+source/maximus/+bug/560272/+attachment/1639954/+files/xfce-maximus-gap.png -- maximus leaves a gap at top in XFCE https://bugs.launchpad.net/bugs/560272 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
