Comment 2 Don Curtis 2020-10-27 09:57:00 UTC 
Operating System: openSUSE Leap 15.2
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.71.0
Qt Version: 5.12.7
Kernel Version: 5.3.18-lp152.47-default
OS Type: 64-bit
Processors: 8 × AMD Ryzen 5 3400G with Radeon Vega Graphics
Memory: 13,6 GiB

Following a hardware upgrade and new installation, I'm no longer experiencing this issue.
 * With the old hardware and openSUSE Leap 15.1, as far as I can recall, with
   this Use Case, plasmashell didn't crash.

Okay great, thanks!
