SUMMARY
When running the plasma system monitor my intel iGPU is 70% utilized. Without it the utilization is only around 2-5%
Such a significant performance impact kinda defeats the purpose of a resource monitoring application.
Other KDE apps have no noticeable performance impact (tried: Settings, Dolphin, Kate, Gwenview).

STEPS TO REPRODUCE
1. Have a machine running Intel Comet Lake UHD Graphics using the Mesa 24.0.9-0ubuntu0.2 driver (Other GPUs & drivers might be affected too)
2. Check intel_gpu_top
3. Start plasma-systemmonitor
4. Check intel_gpu_top again


OBSERVED RESULT
70% GPU Utilization

EXPECTED RESULT
Lower GPU utilization.
