Re: F10 compositing incredibly slow

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



- Dragging a window around (Gnome/Compiz or KDE) results in the window following the mouse cursor by about 1-2sec. It eventually caches up

- Switching desktops in KDE looks less like fluid motion and more like a mess of staic. It does actually work.

- Task switcher takes so long to draw the window changes it is completely unusable.

Thanks for looking into this!

Compositing has been horrible from day one.  I've tried the minimal
Compiz that comes with Gnome, I've tried full-on Compiz Fusion and
I've tried KDE's compositing.  The performance is equally bad in all
three. I've run Compiz on FC6 and F8 using this laptop (Intel
GMA950) and the GPU is more than adequate to make the effects useful.
I'll bet you're on an x86_64 system. There's a whole mess of bugs filed
about this already. Checking F10Target[1], I find a bug named
"i810slow64bit". So you'll want to have a look at those:
https://bugzilla.redhat.com/showdependencytree.cgi?id=469690&hide_resolved=1

Thanks, Will.  I'm not on 64-bit though.

Linux 2.6.27.4-68.fc10.i686 #1 SMP Thu Oct 30 00:49:42 EDT 2008 i686
i686 i386 GNU/Linux

I'll poke around BZ a bit more to see if I can find anything.  My
searches have been fruitless so far though.
