Description chniucg 2024-06-16 18:17:36 UTC 
Application: plasmashell (6.0.90)

Qt Version: 6.8.0
Frameworks Version: 6.3.0
Operating System: Linux 6.9.4-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.0.90 [CoredumpBackend]

-- Information about the crash:
When I press "CRTL + SHIFT + ALT + L" in IntelliJ to reformat my code the plasma shell crashes everytime.
I started to happen 2 - 3 Days ago when I updated my system. Unforunally I don't know exactly what package causes this issue.

The crash can be reproduced every time.

-- Backtrace (Reduced):

Comment 9 Nate Graham 2024-09-01 00:00:33 UTC 
Raising priority as this is tracked on Sentry as https://crash-reports.kde.org/organizations/kde/issues/35063/, and it's the second most common plasmashell crash at this point in time.

waylandtasksmodel: don't remove transient window from windows list

Removing window from windows list causes the window to be destroyed. As
alternative, use the SkipTaskbar role to hide the window.

If PlasmaWindow is destroyed, PlasmaWindow::parentWindowChanged is no longer trigged. So it is no longer possible that Window go back do taskbar if it lose their parent.

To avoid this, use the SkipTaskbar to remove window from taskbar.

Also a missing transients.insert(window, leader) was added.
