            Bug ID: 393626
           Summary: Plasma crashes randomly during coding/browsing
           Product: plasmashell
           Version: 5.12.4
          Platform: Debian testing
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: normal

          Assignee: k...@davidedmundson.co.uk
          Reporter: zheltonozhs...@gmail.com
                CC: plasma-b...@kde.org
  Target Milestone: 1.0

Application: plasmashell (5.12.4)

Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (buster)

-- Information about the crash:
- What I was doing when the application crashed:
Wring code in CLion and switching to browser (firefox) by Alt-tab. The screen
gets black seemingly without connection to what I am doing. 
- Custom settings of the application:

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
