Assunto: Re: KDE4 and nvidia -> strange panel effects?
I have the same problem of Tomasz in Kubuntu Itrepid Ibex. My window become blank
only with theb borders of some windows in GeForce FX 5200.
I want to send data of my hardware and drivers configuration for the developers
and also help. Is here a default app to do that?
Thanks
PS. Thats my first post I'm trying to participate!

For me it is definitely the former case. On Bluewhite64-current (and probably
on plain slackware too) it used to be entirely unusable. With the new beta
drivers the window rendering issues disappeared, I could use compositing
effects, I could actually use the scrollbar in the folderview... but kwin was
chewing up 40% or more CPU in general use, and that number just kept growing
over time. This is on an AMD sempron 3200 with 1Gb of ram.
At this stage, I run kde4.1.1 on Bluewhite64-current using openbox as window
manager, with that, it's fast and usable, but of course I lose all the
advanced kwin features. Some things like virtual desktops also don't work
exactly the way KDE expects them too - virtualbox switches when you get to the
edge of the screen - and in doing so doesn't play nice with xinerama. So if
you were to right-click on the taskbar entry for a window on the right-hand
screen and select move, when you go to drag it to this screen, it ends up on a
different desktop.
These are not terrible problems, just minor inconveniences so for now this
works better for me than kwin. I have also heard that some people are using it
successfully using compiz rather than virtualbox but I haven't tried that
(compiz has always been excruciatingly unstable for me so I haven't been up to
checking the latest versions yet).
Basically, even with KWIN_NVIDIA_HACK=1, all the NVidia settings suggestions
from techbase and the latest drivers you can use KDE4.1.1 on nvidia - if you
have enough CPU to waste. Kwin seems to do something that makes nvidia use a
ton of normal CPU (which is odd, I would have expected it to be offloading
almost everything to the GPU instead).
This may very well still be NVidia bugs, or it may be something in kwin that
should be handled differently.
On various other systems without nvidia drivers however, kwin performs
beautifully, I have even done kwin-effects using XRender on an FBDev driver and
it worked okay (provided of course the CPU was quite powerful since that means
doing effects with no GPU involvement whatsoever) - but kwin+nvidia remains
just about the single worst performing setup you can get for KDE.
I'm mostly giving this information in the hopes of helping to track down the
problem - if it is with nvidia, it may help somebody know what to report to
them, if there is a setting that will remove the problem, maybe somebody can
tell me what it is. Just to make sure I'm clear, the CPU problem persists with
or without effects, effects in OpenGL mode with all the "fastest" options
selected doesn't seem to affect the CPU usage, so I believe they are in fact
rendered by the GPU.
Ciao
