# Crash in Application Dashboard

## What happened?

I'm getting plasmashell crashes when dragging an application in the Application Dashboard.

Steps to reproduce:
1. Open the application dashboard
2. Hover over "All applications" to show all apps
3. Grab an app icon from the app list, drag it somewhere and drop it
4. (pick one)
4.1. Try to scroll down through the list of all applications
4.2. Repeat step 3 multiple times

Result: The dashboard freezes completely. Then the panel disappears. 2-4 seconds later the system recovers by restarting plasmashell and showing a crash report window/pop-up.
(see the attached video for a few examples)

When it comes to step 4, the crash can be caused by either:
- (4.1) just scrolling through the list
- (4.2) grabbing another icon and dropping it (sometimes it requires multiple drag-drops, sometimes just grabbing/clicking an icon)

Notably, to recreate the crash you need to have the "All Applications" view displayed *while* dragging the app launcher/icon. If you do any of the following, the crash will NOT happen:

(Case 1; won't crash because the "All Apps" section was not visible at first)
1. Have anything other than "All applications" displayed
2. Drag-drop any icon anywhere
3. Go to "All Applications"
4. Scroll through the list
Result: No crash. The "All Applications" list loaded after the drag-drop interaction.

(Case 2; won't crash because the "All Apps" section was reloaded)
1. Have "All applications" displayed
2. Drag-drop any icon anywhere
3. Hover over anything other than "All applications" (make sure you haven't scrolled yet)
4. Go back to "All Applications"
5. Scroll through the list
Result: No crash. I assume the "All apps" component unmounted and re-mounted due to the user navigating away from it and then navigating back.

(Case 3; won't crash, but the list unloads for some reason)
1. Have anything other than "All applications" displayed
2. Drag-drop any icon anywhere
3. All the icons in the middle section disappear from the currently active app category
Result: No crash, but there is a bug: all the icons disappear from the middle section. So I'm not sure if the categories would crash too, since their app list cannot be interacted with after a drag-drop.

(Case 4; favorites won't crash, the bug seems isolated to the middle section)
1. Have anything other than "All applications" displayed
2. Have enough applications under "Favorites" (the left section) so that it displays a scroll bar
3. Drag around any icon
4. Scroll through the "Favorites" section
Result: No crash. It looks like the bug is entirely isolated to the middle section of the dashboard.

In my case I first discovered the issue when I was simply trying to pin my apps from the "All applications" to the "Favorites" section. (Pinning the apps with the "right-click -> Add to favorites" action does not cause a crash). At first this happened pretty much instantly. But the more I tried to recreate the bug, the longer it takes to crash. When I started recording, it already started taking 2-5 seconds for plasma to crash after scrolling. At first it crashed instantly or took up to a second.

## System specs

### KDE

KDE Plasma 6.4.5
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2
KWin (Wayland)

### OS

aurora:stable
Aurora (Version: 42.20251012.1)
Linux 6.16.7-200.fc42.x86_64
Mesa 25.1.9 (LLVM 20.1.8)

I've tested both an existing install of Aurora and a clean install. In both cases I can reproduce the bug. I selected Bazzite as a platform since it's a sibling distro of Aurora and from my recollection this also happened to me on Bazzite once (I just ignored it and assumed it cannot be recreated. Adding stuff to favorites is something I only do once or twice and often I just close the dashboard rather than keep interacting with it).
In a day or two I'll try testing a couple of other distros, like KDE Linux, unless someone beats me to it. (Just to confirm this isn't something related to my distro specifically)

### Hardware

I managed to recreate the bug on multiple devices, one all Intel with integrated graphics and one all AMD with a dedicated GPU. So I don't think it's a hardware issue.

### Logs

I tried generating a proper crash log, but the result is always "information is not useful". So the following is the only information I have for now:

Application Dashboard crashing after a shortcut is dragged

The plasma shell crash happens after an icon is dragged, while the user is scrolling. However, it sometimes doesn't crash immediately and requires hovering over an icon.
Comment 3 Akseli Lahtinen 2025-10-16 08:38:34 UTC 
Thanks for the detailed bug report! Can confirm the crash with these steps:

1. Open application dashboard
2. Go to all applications
3. Drag icon from the list to favorites, then back to the app list
4. Repeat step 3 few times
5. Eventually things freeze and then crash
