We need more information to see which part of the system is at the root cause of this problem. Could you attach either a screenshot or a phone photo of what the monitor looks like with the graphical glitches? Also, do you have the proprietary nvidia drivers installed? Note: According to the screenshot, the correct KDE Frameworks Version is 6.12.0

Thanks for the video, it definitely shows what's happening. I'm attaching it as a file to this report so there's no chance of an expired link. Do you have the TRanslucency effect enabled under System Settings - Desktop Effects? Do you still see these glitches if you turn that off? Moving this back to the kwin component, since this involves the compositor. Please don't switch it.
