I don't know "who to blame" for this. I'm almost certain that it's not Plasmas fault.
As you can see I'm an active student that was participating on the Kourse 2: Screencasts. That's why I had to disable the compositing option of KWin as krecordmydesktop has some problems with it.
But I have now finished with the screencasts and turned effects back on.
And things that I had no problems before but were there in past started to appear again.
The "screen garbage" is back
Plasma crashes a lot and the error that it gives is just bug.kde.org.
Plasma dosen't remember the newly added widgets.
I have few suspects but I need your help at finding the real culprit.
-It might be the new kernel 27-11
-It might be the Bespin theme 0.1 (I think it's not I'm not sure I changed to Oxygen, but the screen garbage problem continues)
-It might be KDE-nightly, but I don't think so, as I still use the ordinary KDE4.2beta2
-Or it might be something else

So please help me.

Other info of my system:
KDE4.2beta2
Kubuntu
Nvidia 177.22 GeForce 6600
Anything else that you need??

if all the problems appeared after enabling the effects you probably should try the newest nvidia driver
http://www.nvidia.com/object/linux_disp ... 80.17.html
(the new driver is great.. smooth scrolling, smooth resizing of widgets, no artifacts at program-starts, no choppy effects)

and try disabling the blur plugin (if turned on) it was responsible for most of the plasma garbage on my computer..

Thanks to you (and dibl from Kubuntu forums) I istalled the 180.22 driver and so far so good!

Nope, the "memory" issue with panel is still here.
When I log out and back in I loose all newly added widgets...
I have no idea what's wrong...

remembering widgets is a different task..

have you tried deleting your
~/.kde/share/config/plasma-appletsrc
~/.kde/share/config/plasmarc

??

Forgot about that...
If I'll still have problems, currently it again seems OK I'll do that.

The problems stoped...
I mark this solved!
