Version: 4.4.00 (KDE 4.4.0) (using 4.4.00 (KDE 4.4.0), Arch Linux) Compiler: gcc OS: Linux (x86_64) release 2.6.32-ARCH I use ksysguard normally (only some coulomns changed from basic setup) I tried, it had no backtrace. Until kde 4.3.4 all worked fine, but at kde 4.4.0 around every 3rd start of ksysguard I get 100% for total cpu usage. I have 2 cores. My cpu-usage widget shows much less, and system load tab's cpu history even shows the same: 10-20% usage/core. And nothing overloads the cpu, almost nothing's going.
Is it still a problem for 4.8.5 or 4.9.2 ?
Cannot reproduce with 5.12.4. Please reopen if this bug still occurs.
