Seeing the same behavior on a 1001p Eee PC. Specifically, I am seeing very slow/inconsistent performance when using the launcher bar at the left edge of the screen. It takes 2 or 3 clicks on an icon for it to actually switch to or start the application that I clicked on. In Top I see mutter using up 50% or more of the cpu.
I tried setting clutter_vblank and see no improvment. However, after running mutter with the command CLUTTER_VBLANK=NONE mutter --replace I saw lots of errors in the terminal window, like these: (mutter:6015): Clutk-DEBUG: CtkText: focus-in Mesa 7.9-devel implementation error: Bad renderbuffer format: 21 Please report at bugzilla.freedesktop.org (mutter:6015): dee-WARNING **: Unable to connect to peer (:1.20): Could not get owner of name ':1.20': no such name (mutter:6015): dee-WARNING **: Unable to connect to peer (:1.20): Could not get owner of name ':1.20': no such name (mutter:6015): Clutk-DEBUG: CtkText: focus-in Window manager warning: Log level 16: g_object_weak_unref: couldn't find weak ref 0x7124c0(0xa1db3b8) Window manager warning: Log level 8: g_object_unref: assertion `G_IS_OBJECT (object)' failed (mutter:6015): Clutter-CRITICAL **: clutter_actor_unparent: assertion `CLUTTER_IS_ACTOR (self)' failed This last line shows up every time I mouse over or click one of the icons in the launcher bar on the left edge of the screen. -- [Intel GMA 945/950] Unity Interface Is Extremely Slow (Ubuntu Netbook 10.10) https://bugs.launchpad.net/bugs/657976 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
