Default Issue between KDE 4.x

Dear Debian KDE Maintainers,
First, thank you*for your job, I know that maintaining huge packages is very much time consuming and not easy.
* Kde experience

Before reporting a bug in KDE I would like *to have your opinion on how best it should be done.I have been using Kde for many years now, basically from its creation until 4.3.x. I have also installed*
4.4.x. *Because I maintain and use paraview (a big package also) I add to get rid of 4.4 and go back to 4.3 (due to Qt dependency).
For the record, I have a Lenovo T61p *with an Nvidia Quadro FX 570M card with 8Go of RAM and Debian unstable
I have enabled some of the fancy effects
** suspend
With Kde 4.x I always had problems with suspend, either it just didn't work (laptop froze) or*after 2 successfull suspends I had to shutdown/reboot the laptop
I always thought that it was due to bad Nvidia drivers(I am using the ones shipped by *Debian ).*
** Very slow desktop
With 4.3.x and 4.4.1 (and possibly earlier*versions of Kde 4 I cannot remember ) I*
had also*plasma or the desktop that would become incredibly slow to the**point of being unusable then sometimesafter a little while it would be back.
** Desktop/Plasma does not resize properly

I teach courses at the university and I use quite often *twinview of nvidia through nvidia-settings in order to show*some slides or make demos. When I disable the video projector and get back to laptop screen only, the plasma desktop*
keeps the preview large screen dimension *and the plasma panels are far too large and don't show the almond, systray and parts*of the taskbar. I usually "fix" that by adding some spacer (still no almond though). This is just painful.

*Gnome Experience
Basically it was becoming hard to use Kde on a daily basis and I decided to have a little experiment: install gnome 2.28 (I have some*gnome 2.30 packages installed too). I have also installed compiz and enabled all kind of effects.

Now for two weeks,**- the desktop never became slow, it is very responsive and is quite fancy*- suspend just works, it is a bliss.*- no issues with desktop resizing
*In my opinion, there is something wrong KDE/Plasma and its use of OpenGL. Before this experience, I blamed nvidia and was looking*for changing my laptop and use ATI*but now I definitely blame KDE/Plasma*

Any suggestions how to report this ? the resize problem is definitely a plasma bug but what about suspend and the slow desktop ? plasma too ?
any suggestions ? thoughts ?

Best regardsC.

Just for the record, I am experiencing similar problems: X (or KDE) becoming
almost unusably slow. FWIW, I have a Lenovo Z61m with a Radeon Mobility X1400
chipset.

When I'm just working on the notebook display, everything is fine usually, but
when I connect a separate display, performance decreases a lot.

Suspend works fine for me, though. With 4.4.2, I even get a nice notification
that the display settings have changed afer having plugged the notebook in the
docking station and waking up from suspend.

Have you tried not using desktop effects? Does that make a difference?

Cheers,
Carsten
