@Dmitry, I don't know why compositing-manager was changed from false to true, so I didn't know if it was important to revert it or not. I thought that people that want a compositing manager use compiz, but since metacity is implementing it with xrender instead of opengl, maybe it will work fine with older clients as well. In the past I tested with xcompmgr and it did have some issues so we avoided using it as the default; using more RAM which was important with low-RAM clients, breaking vsync with full screen apps etc. Now that I know that metacity will be using compositing in 16.04, I'll test with and without it and if I find any notable issues with it I'll mention it in some other bug report.
@Alberts, > Did not you say that this is also problem in compiz? I did mention that I saw a white background for 0.1 seconds, sorry for that. Maybe it was caused by some bug in the blending effect between the lightdm/user background, dunno... The gnome-panel wrapper trick was a nice breakpoint that cleared things up. About the patch, I tested it and it works fine here: apt source metacity apt build-dep metacity patch compositor-xrender.c < 0001-compositor-try-to-user-root-window-background.patch debuild -b -tc dpkg -i libmetacity*.deb metacity*.deb metacity-common*.deb -> create gnome-panel wrapper service lightdm restart Thank you very much guys, you're great! :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1563735 Title: Recent gnome-flashback clears the background on login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-flashback/+bug/1563735/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
