Bug ID: 427914
Summary: Kinfo File Indexer Monitor takes lot of CPU when
indexing is disabled
Product: kinfocenter
Version: 5.20.0
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: File Indexer Monitor
Assignee: stefan.bru...@rwth-aachen.de

system load when viewing the file indexer tab
SUMMARY
The tab in Kinfo showing status of File Indexer takes 50%+ CPU load even when
showing just "File Indexer is not running" with button "Start File Indexer".
(that is 50%+ on *all* 16 cores of AMD Ryzen 7)
STEPS TO REPRODUCE
1. disable file indexing service
2. launch kinfo - normal ~0% CPU usage, showing version of KDE
3. switch to File Indexer Monitor = half the CPU used for "nothing"
OBSERVED RESULT
~35% CPU is used by process kinfocenter
EXPECTED RESULT
~0-1% CPU usage would be expected, when it just reports that the file indexing
is not running
