Comment 1 Bug Janitor Service 2024-05-02 10:00:18 UTC

Thank you for the bug report!

Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting), and Plasma 5.27.5 is no longer eligible for support or maintenance from KDE. It's possible that the issue exists only in Debian at this point.

Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream.
Thanks for understanding!

Thanks again!

plasma-discover (5.27.5) using Qt 5.15.8

I opened discover without an internet connection. I did this after opening and closing dolphin, but didn't have any other processes running.
