KDE desktop rendering problem

Hi, I am using OpenSUSE for the first time. I quite like it but KDE on 11.3 is really giving me a hard time. My desktop becomes very sluggish after about an hour of usage and the KDE widgets/desktop are no longer rendered properly, with color spilling and bloated borders etc. To give you a better idea, here is a screenshot of my desktop -

here’s another -

After a lot of digging around google and the OpenSUSE forums, I suspect that this might be an issue with drivers for Intel Graphics, though I couldn’t find anyone experiencing exactly the same problem as me. I am running a P4 2.4 GHz with onboard intel graphics. Any help would be greatly appreciated.

Thanks in advance.

Have you added any repos?

IS this with or without effects?
Did you test with the default theme aya or oxygen

I am not running desktop effects, and yes I have tested both aya and oxygen theme. Here’s my repo list -

Which intel chip is it?

It belongs to the intel i845 family. I checked my hardware conf in YaST and it shows that a driver for i915 is being used. Could that be the source of the problem ?

Please post result of

/sbin/lspci -nnk

I don’t want the wireless section this is showing, the video section is right at the top of the output, scroll up and find it

here it is -

I suggest you have a read here

Although I have 2 different Intel chips myself, neither are the same as yours.
