            Bug ID: 512796
           Summary: Overview causes plasma to hang
    Classification: Plasma
           Product: plasmashell
      Version First 6.5.2
       Reported In:
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: generic-performance
          Assignee: [email protected]
          Reporter: [email protected]
  Target Milestone: 1.0

SUMMARY
The overview causes unnecessary disk access, making it slow the first time
opening, and potentially causing the whole compositor to hang when there is IO
heavy operations running. 

STEPS TO REPRODUCE
1. Have two monitors
2. Run a game in the primary monitor
3. Compress a huge directory into a tar.gz archive
4. Open the overview

OBSERVED RESULT
The whole compositor hangs for a long time (I waited around 3 minutes until a
new frame was rendered by the compositor, and had to force shutdown my machine)

EXPECTED RESULT
Have the effect run without causing the system to hang
