[unity-2d] bamfdaemon & dbus-daemon high CPU on scrolling window, or switching window, or tab in window, or loading new app (always when screen redraws)

[Nicholas Shatokhin]

When screen redraws or some application works in background, I see huge processor's loading and system works like a slideshow. Also I see it when I scroll window.

I use Unity 2D. In Unity 3D problem is bigger.

[Nicholas Shatokhin (robotex)]

I can't use gedit. When I try scroll text document processor loads on 200% (it's double core) and gedit needs few minuter to scroll on one pixel down. It's horrible.

[Nicholas Shatokhin (robotex)]

*few minutes

[Rick Spencer (rick-rickspencer3)]

This does not sound like a Unity bug to me. Did you try running Ubuntu without the nvidia driver?

[Phillip Susi (psusi)]

Please don't subscribe every group under the sun to bugs.

[Nicholas Shatokhin (robotex)]

I removed nvidia drivers and installed nouveau. Problem still exist.

[Daniel van Vugt (vanvugt)]

Nicholas, please attach some details about which processes are using all the CPU, and how much. For example, output from the "top" command.

[Nicholas Shatokhin (robotex)]

On this screen I opened empty gedit window with no file and start to scroll quickly (nothing redraws).

[Nicholas Shatokhin (robotex)]

On this screen I opened chromium window, opened website and start scrolling quickly.

In beta2 guilty another process: Xorg. I report new bug: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/973506

See the debug info and screens.
