In Plasma 6 + Wayland, the CPU chart in System Monitor is showing unexpected horizontal lines.

Other charts (the ones with light blue and orange colors) are not affected.

In Plasma 5 + XOrg, the CPU chart is fine.

STEPS TO REPRODUCE
1. Install Wayland + Plasma 6 + proprietary Nvidia drivers
2. Open System Monitor > History
3. Observe glitch in the CPU chart (see attachment)
