Hi folks!
It should be added here that the effective solution in this topic is to switch
to OpenGL ES compositing in KWin. The OP is using a really really old Intel 3th
gen 945G iGPU which even don't supports OpenGL 2.0 fully. However, the awesome
Mesa drivers offers stable OpenGL ES 2.0 support even for that old vintage
hardware. ;-)
To get there, open the following file:
sudo nano /etc/profile.d/kwin.sh
And then add:
export KWIN_COMPOSE=O2ES
Save and reboot. By the way, it was confirmed by the OP "johnathan" that this
works. More information can be found at the corresponding Mesa bug report:

@Nate Graham
I really don't understand why the OpenGL ES renderer is not present as an
official option in the UI. It is absolutely useful especially on older and
weaker hardware like we have here. The only drawback is that some more complex
themes / global designs may show artifacts. But that's acceptable as long as
the standard Breeze theme is fully working. I can confirm this for latest
Kubuntu 22.04 running at a dual-GPU based iMac 12,2 computer. Absolutely no
issues there even with the enforced OpenGL ES compositing backend. :D
