I have some more observations: 1. I tried gnome-shell for a day, and at one point glxspheres was suffering in performance, but not as badly as under compiz. The animation was periodically freezing for a half second - it would then report one (say) 40fps reading, and then immediately jump back to 59fps. I didn't notice any slowdown in the UI, though.
2. Today in compiz I had the slow window dragging issue after a few hours of use, ie when you drag a window it only moves the window jerkily, and if you move the mouse too fast the window stops moving altogether. However, and perhaps strangely, glxpheres reported a consistent 59fps. Animations were slower than usual although the super-S and super-W animations were still nice and fast. The only odd thing that had happened in the session was that compiz had earlier lost track of a window while I was dragging it when another window was opened - I had to manually kill the process and restart it because compiz couldn't re-display it. I tried a ps auxw |grep compiz and it reported 721 MB VSZ and 71MB RSS, whereas after startup it's more like 800MB and 120MB. I'll try the PPA version to see if it helps. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/861061 Title: compiz 3d performance regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/861061/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
