-- Information about the crash:
- What I was doing when the application crashed:
I opened firefox used it for a while. Then I  opended muon.
And then I  pressed  the firefox application icon in the panel -  plasma crashed.
It is reproduceable:
Opening 2 or more applications. And focus e.g. on  firefox. 
When plasma does'nt crash at once, I change the focus several times.
This plasmacrash  happens only  on this laptop (HP Pavilion 17-g164ng).

Window thumbnail, the component with the crash changed a lot in frameworks 5.27

which is after this crash report.

Given I've not seen any duplicate reports with newer frameworks I think it's fixed. Please reopen this bug if it still occurs with frameworks 5.27 or later.
