SUMMARY After running System Monitor (ksysguard) for several minutes, the value for the eighth thread becomes 3e+06% and its line in the graph goes to the top. Also the value for memory usage drops to zero. Closing the application and reopening temporarily corrects the problem. STEPS TO REPRODUCE 1. Open ksysguard (system monitor) 2. Leave application running 3. OBSERVED RESULT Unreasonable values for some system metrics EXPECTED RESULT Accurate values for all system metrics SOFTWARE VERSIONS (available in About System) KDE Plasma Version: 5.8.7 KDE Frameworks Version: 5.32.0 Qt Version: 5.6.2 ADDITIONAL INFORMATION
Fixed in a later version of Plasma. If you prefer LTS versions, I recommend 5.12. If you're more adventurous, 5.14 was just recently released. 5.8 is pretty old at this point.
