plasmashell (5.22.5) using Qt 5.15.2

- What I was doing when the application crashed:

Just resumed my computer out of sleep mode and clicked an icon in the tray. This time is specifically was the KDE Connect icon, but Plasma has crashed (and restarted) when I clicked other tray icons as well (so I don't think it's KDE Connect specific).

In this case, it didn't happen, but usually when Plasma crashes, it takes down other applications with it such as Dropbox, MS Teams, and Waterfox (a Firefox clone).

It seems to happen often after resuming from sleep, but I can't say it happens every single time.

plasmashell (5.23.3) using Qt 5.15.3

I'm always up to date with KDE Neon, and this failure keeps happening.
I'm not sure if the merge-request that this issue was marked as a duplicate refers to can actually fix this specific issue.

It's Bug 414805. The issue is in Qt itself, not any KDE code.

Okay, thanks for pointing out that the bug is in QT and not KDE.

Since I keep getting this error repeatedly and https://invent.kde.org/qt/qt/qtbase/-/merge_requests/33 has merged 5 months ago, (and I can assume it's already integrated for general use in KDE Neon), is there any other issue that I should be aware of to see and/or help with more information that deals with this specific issue?

Darn, looks like you do have the supposed fix, then. I'll re-open the parent bug report.

Actually looks like I was wrong; there's no QScreen::handle() in your backtrace, so I guess it's a different bug.
