Plasma-desktop 6.5.6-1 breaks panel widget dragging in edit mode

Support KDE Plasma
1

Is anyone else having a problem with the panel after updating to plasma-desktop 6.5.6-1?

On plasma-desktop 6.5.5-1, when I right-click a panel and then click Show Panel Configuration, hovering the mouse over a panel item shows the drag handle, so the item can be repositioned in the panel as desired.

See the screenshot below for what I mean:

The behavior shown in the screenshot is the expected one.

However, after updating to plasma-desktop 6.5.6-1, this is no longer possible.

Steps I used to reproduce the problem

Recently, I went to https://manjaro.org/products/download/x86 and downloaded the latest stable KDE Plasma ISO.

After downloading it, I created a bootable USB drive using Manjaro’s own Image Writer.

Then I formatted my computer and installed the system.

As soon as the installation finished and the system booted for the first time, I tested the panel editing functionality, and it was working correctly.

Then I installed all pending updates using the Pamac GUI.

Among those updates was plasma-desktop 6.5.6-1.

After installing all updates, including plasma-desktop 6.5.6-1, the ability to drag widgets/items in the panel stops working.

However, if I add plasma-desktop 6.5.6-1 to Pamac’s ignore list, the panel continues to work normally as expected.

Based on the tests I’ve done, the problem occurs in both Wayland and X11.

Yes, this is quite well known and has been talked about quite a bit recently.

It’s gone with 6.6 - but apart from that, it’s a pretty solid release.

You can have a go at moving things by editing the config and swapping the items manually (numbers list showing the order):

cp ~/.config/plasma-org.kde.plasma.desktop-appletsrc ~/.config/plasma-org.kde.plasma.desktop-appletsrc.backup

Backup because this kind of hack is always a touch risky…

Edit and find AppletOrder to edit the numbers in AppletOrder

systemctl --user restart plasma-plasmashell.service should refresh everything and get the new config loaded.

Thanks for the reply.

I tested again on the stable branch.

My current versions are:

  • plasma-desktop 6.5.6-1.1
  • plasma-workspace 6.5.6-2

After updating plasma-desktop and rebooting the system, the problem still persists.

I still cannot reorder the panel widgets/items normally in edit mode after the update.

So, at least in my case, having plasma-workspace 6.5.6-2 does not solve the issue.

Since I created a full system snapshot with Timeshift, I am going to roll back to the point where plasma-desktop was being ignored in Pamac updates and was still on version 6.5.5-1.

For now, I will keep plasma-desktop on version 6.5.5-1 and continue ignoring updates for it in Pamac.

Still, it is useful to know that this is already a known issue, and I appreciate the suggested workaround of manually editing the order in the ~/.config/plasma-org.kde.plasma.desktop-appletsrc file.

I’m waiting for version 6.6 to be released on the stable channel.

Thanks again.

Nobody said 6.5.6-2 would solve the issue.

Thanks for the clarification.

You are right: in this topic, nobody said that plasma-workspace 6.5.6-2 would solve the issue.

Ben only said that the problem is gone with 6.6.

I mentioned plasma-workspace 6.5.6-2 because I had seen a report in another topic saying that it might fix the issue there, so I decided to test it on my system as well.

In my case, on the stable branch, the problem still persists with:

  • plasma-desktop 6.5.6-1.1
  • plasma-workspace 6.5.6-2

So for now, I will stay on plasma-desktop 6.5.5-1 and wait until 6.6 reaches the stable branch.

Thanks again for the clarification.

Same bug here. Cannot drag and move any widget on desktop toolbar/panel. When the mouse is over the widget, the whole panel is detected instead of the widget, so I’m not able to move them.

I tried:

  • Delete current panel and create new from scratch
  • Reset plasma settings
  • Reset kwin settings
  • Reinstall whole plasma environment
  • Create new user and log in
  • Create x11 environment and log in

But still not working.

Has anyone solved it? Maybe a downgrade? Which version?

Welcome to the Manjaro community @gmm96

Downgrades are not recommended as they place your system into an unsupported state. This especially applies to desktop environments such as Plasma, where the previous version may have been built against a different version of Qt or other libraries, causing breakage when the downgraded Plasma can’t find the older versions of the packages it was built with.

Instead, if you really need the movable widgets, I would recommend that you switch to Testing branch, which is currently on Plasma 6.6.3:

mbn info plasma-desktop -q | grep -Ev 'Name|Repository|Packager'
Branch         : archlinux
Version        : 6.6.3-2
Build Date     : Sat 28 Mar 2026 23:48:58 
Branch         : unstable
Version        : 6.6.3-2
Build Date     : Sat 28 Mar 2026 23:48:58 
Branch         : testing
Version        : 6.6.3-2
Build Date     : Sat 28 Mar 2026 23:48:58 
Branch         : stable
Version        : 6.5.6-1.1
Build Date     : Tue 31 Mar 2026 14:19:08

Switching branches is a simple process (and don’t worry - Testing is quite stable - I’ve been running it trouble-free for nearly 2 years).

To switch to Testing branch:

sudo pacman-mirrors --api --set-branch testing

or, to switch to Unstable branch:

sudo pacman-mirrors --api --set-branch unstable

After you changed the branch, rebuild the mirrorlist and update your packages:

sudo pacman-mirrors --continent && sudo pacman -Syyu

File Path : The configuration is stored in ~/.config/plasma-org.kde.plasma.desktop-appletsrc .

Open that with Kate, then hit F4 to get a terminal pane open too. You can then do:

cd ~/.config
cp ~/.config/plasma-org.kde.plasma.desktop-appletsrc ~/.config/plasma-org.kde.plasma.desktop-appletsrc.bak
kate config

So then it’s open in the editor, CtrlF to filter, type ‘Order’
You should find something like this, plotting the order of the applets enabled.
AppletOrder=56;112;23;

Simple, the middle applet is 112 - move it to the end:
AppletOrder=56;23;112;

CtrlS to save, then in the terminal:
systemctl --user restart plasma-plasmashell.service

If it works, come back and give it a :white_check_mark:

In my case, I also have the problem when I update to the stable version:

  • plasma-desktop 6.5.6-1.1

Therefore, at the moment, the only practical solution I know in the stable version is manually editing the AppletOrder, as described by Ben.

Thank you for adding those test results. They are very helpful.

Currently, I am using version 6.5.5-1 of plasma-desktop and the problem does not occur in this version.
