Bug ID: 496744
Summary: Excessive GPU usage when running plasma-systemmonitor
Classification: Applications
Product: plasma-systemmonitor
Version: 6.2.3
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Target Milestone: ---
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.
