Do you use a custom widget style?

> Do you use a custom widget style?

Breeze Dark is my Plasma Style. I am confident that it is not considered to be custom. Regardless of that, I have reinstalled my operating-system, so this report may not be actionable anymore.

Comment 3 Nate Graham 2023-09-27 21:02:56 UTC

Can you still reproduce it in Plasma 5.27?

Per

I doubt I ever knew exactly how to reproduce it initally, much less now. However, doing what I have recorded doesn't appear to yield a crash, not that (per the aforementioned) it ever did reliably.

Comment 6 Roke Julian Lockhart Beedell 2024-04-19 19:26:22 UTC

There's no icon view anymore, so closing.
