I am running Tumbleweed on several laptops. On one of the laptops, I cannot manually adjust the length of the panel (the resizing arrows do not seem to work, which I gather is a recurring bug?). Also the left and right panels seem offset to the right of the screen border while the bottom panel is offset downwards.
I have looked online and examined both lasma-org.kde.plasma.desktop-appletsrc and plasmashellrc in my user account but I cannot find the settings that correspond to my problem.
I created a new user and added corresponding empty panels, which displayed the same behaviour, which suggests to me that the problem may be something misconfigured at the system level.
Some details that may be relevant are:
Operating System: openSUSE Tumbleweed 20260813
KDE Plasma Version: 6.7.4
KDE Frameworks Version: 6.28.0
Qt Version: 6.11.1
Kernel Version: 7.1.8-1-default (64-bit)
Graphics Platform: Wayland
Graphics Processor 1: Intel® UHD Graphics
Graphics Processor 2: NVIDIA GeForce RTX 3060 Laptop GPU
Manufacturer: Acer
Product Name: Predator PH315-54
Is anyone able to point me towards where I might find information that would help me resolve this problem?
Cheers,
Brad

That pertains to your laptop’s internal display? Its geometry looks normal to me: 0,0 1920x1080, scale 1, with no rotation or overscan. The other two outputs are external displays positioned to the right of it.
Does the problem persist if the two external displays are disconnected?
@deano_ferrari
You are correct that the problem is on the laptop internal display.
Disconnecting one of the external displays (HDMI) does not change the problem.
Disconnecting the USB-C external display improves on the problem but only partially: the left panel snaps to the screen edge while the right and bottom panels remain overlapping the screen edge.
I have had this configuration for several years and it worked well, but this problem arose sometime in the past year or so.
Thanks for your help.
Brad
Some advice: the longer you wait the harder it will be to debug where a working situation went for a break, if some update was involved a year makes it impossible to detect which one.
As this is more of a minor annoyance rather than a drop-dead issue. I thought I’d wait to see if it was resolved through subsequent updates. If it is too difficult to diagnose, I guess I’ll have to live with it.
Cheers
This does appear to be a regression Plasma/KWin’s handling of the multi-monitor layouts. Does the same problem exists for Plasma X11 sessions?
It may also be worth testing with the USB-C display disconnected and then reconnecting it after logging into Plasma, to see whether the panel layout changes when that output is added?
Similar KDE issues?
@deano_ferrari
Using X11 does indeed solve the problem.
Unplugging the USB-C monitor and relogging in with wayland did not affect the problem.
I will have a look at the KDE links you provided shortly, but it appears I’ll be reverting back to X11 for a while.
Thanks for all your help and ideas.
Cheers.
Brad
I don’t know, but the other two KDE panel posts seem to be a separate issue.
Thanks tho’.
Cheers.
