I can confirm this bug on my Ubuntu Natty / 11.04. If I hide the desktop icons, the solid color desktop background is not redrawn and the windows leave trails (see the attached screenshot).
For me, it is not a very big deal, because I have the desktop icons enabled and in that case, as Jacob Williams correctly stated, the background is redrawn properly. But it surely is a bug and needs to be resolved! ** Attachment added: "Screenshot of windows leaving trails when the "show_desktop" is disabled." https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/775639/+attachment/2130540/+files/Screenshot.png -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/775639 Title: Desktop background does not draw when set to solid color -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
