Application: plasmashell (5.18.4)

Qt Version: 5.14.1
Frameworks Version: 5.69.0
Operating System: Linux 5.6.4-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Working with Opera browser. 

Usually, Plasma crashes when Opera browser peforms heavy rendering operations (maps or video). It does not matter, if hardware acceleration is enabled or not.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
