Description Andres Nogueiras 2018-07-10 09:09:17 UTC 
Application: plasmashell (5.8.7)
 (Compiled from sources)
Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.138-59-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- Unusual behavior I noticed:

Since a couple of months, the panel of the application get stuck (rises and block, or get hidden and bloc) ramdomly.
Sometimes I just close the panel and then things go back to normal, but sometimes it even freezes the whole plasma desktop.
It does not matter if the panel is the openSuSE one or the default panel.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 11 Nate Graham 2021-12-03 20:49:35 UTC 
The reporter of duplicate bug 446421 can reproduce the issue 100% by running the following python script:

> import pygame
> from pygame.locals import *
> pygame.init()
> 
> screen = pygame.display.set_mode((500, 500), flags=FULLSCREEN)
> clock = pygame.time.Clock()
> 
> run = True
> 
> while run:
>     for event in pygame.event.get():
>         if event.type == QUIT:
>             run = False
>     pygame.display.update()
>     clock.tick(60)
> pygame.quit()

I can reproduce it, though.

So does it also crash for you, with this script?
The thing is that even without running it again, the system always remains in this broken state. After restart and even after restoring a backup

Actually this is not really a duplicate. It seems to happen sometimes for the reporter of THIS bug for me it's permanent. Maybe I understand it wrong. The shell always breaks on start. It always had problems with fullscreen windows but this is the worst bug/error I had.
Comment 14 Nate Graham 2021-12-03 21:05:21 UTC 
So sorry, typo: I CAN'T reproduce it with that script.

> So sorry, typo: I CAN'T reproduce it with that script.

Did you execute it correctly? Did it open a window?
Comment 16 Nate Graham 2021-12-04 15:04:00 UTC 
I think so. I saw a black fullscreen window.
Comment 17 Alpha-Craft 2021-12-04 17:58:31 UTC 
(In reply to Nate Graham from comment #16)
> I think so. I saw a black fullscreen window.

Some additional information, which could help reproduce the error:
Use Kubuntu 21.10
Upgrade to KDE Plasma 5.23.4 (latest version):
"sudo apt-add-repository PPA:kubuntu-backports/ppa
sudo apt update && sudo apt full-upgrade"
Use two monitors.

This COULD help reproducing the error. Best would be in a VM.

I  get a bit different backtrace than the original poster with Plasma 5.23.90 (Frameworks 5.90.0, Qt 5.15.2, kernel 5.16.1). It happened sometime over night. I just went sleeping and turned of monitors and when I woke up and got back the crash dialog awaited with this backtrace:

Application: Plasma (plasmashell), signal: Segmentation fault

The crash (at least the one reported in dup issue https://bugs.kde.org/show_bug.cgi?id=446993) no longer happens for me on:

Operating System: Fedora Linux 35
KDE Plasma Version: 5.24.2
KDE Frameworks Version: 5.91.0
Qt Version: 5.15.2
Kernel Version: 5.16.12-200.fc35.x86_64 (64-bit)

for how the bt looks, the crash occurred exactly when you turned out the monitors (or videocard?), and those are the type of monitors that wen you turn them off/go to sleep the system thinks they have been completely disconnected, so while sleeping, plasmashell destroyed all of its views and tried to create new ones on resume.

this still doesn't explain the crash tho
Comment 32 Fushan Wen 2023-04-05 02:37:05 UTC 
Could be fixed by https://invent.kde.org/qt/qt/qtdeclarative/-/merge_requests/40
Comment 33 Nate Graham 2023-04-16 03:42:36 UTC 
If so, this should already be fixed in Plasma 6.

QQuickItem: Fix effective visibility for items without parent

Items are visible if they are children of a visible parent, and not
explicitly hidden. The effectiveVisible member stores the state and is
updated when conditions that impact the item visibility changes.

The old code returned true for items outside a visual hierarchy, which
broke signal emission when items were removed from a parent, e.g.
because the parent got destroyed. With this change, items removed from
a visual hierarchy will emit the visibleChanged signal.

Note: QQuickItem initializes the effectiveVisible member to true, even
if the item was created without parent item. Visual items are required
to be added to a visual hierarchy via setParentItem. For this reason,
newly created items never emit visibleChanged when they are added to
a parent.

Adjust the QQuickItem::visible test - it creates an item hierarchy
without window. Such items are never visible, so add a window and
parent the test item hierarchy to the window's content item.

This fixes the expected failures in the tests. It does introduce an
incompatibility with QGraphicsView and QGraphicsItem, which continue
to return true from QGraphicsItem::isVisible for items that are not
in an item hierarchy.

[ChangeLog][Qt Quick][QQuickItem] The visible property of Items without
a parent now always returns false, and the visibleChanged signal gets
emitted when the parent item of a visible item becomes null.

Fixes: QTBUG-108213
