All windows borderless and "stuck" after latest update

Hi there everyone!

I'm experiencing a graphical issue since the latest Manjaro KDE update. The issue is as follows:

All of my windows have become borderless (screenshot 1). I'm unable to resize, drag, minimize, close or move them in any way, shape or form. I need to resort to ending processes to close programs.

I can click program icons in the taskbar and open programs. However, right clicking their taskbar icons > close doesn't work -- it's as if they weren't open in the first place (screenshot 2).

Alt+F3 does not trigger border settings. Alt-tab has no output.

The keyboard's output goes to the topmost window, even if I select a "typeable" field in another window. For instance: if I first open Firefox then open the terminal and type anything on it, I can no longer type into Firefox's search bar even if I've selected it with the mouse. All text output goes to terminal until I close it through the menubar.

I've tried creating a new superuser and running a "fresh" KDE through it but the issues persists there -- e.g. windows are still borderless and unmovable despite using default settings.

I've tried changing themes -- to breeze, etc. -- but the issue still persists.

This is the closest instance of the issue I could find in the entire forums (screenshot 2).

It's worth noting I'm currently running KDE on two machines and only one of them has expressed this behavior after the latest update.

I was running KWin when the issue started and tried using lightdm but the issue persisted.

In case it's useful, here's my inxi -Fxxxz output:

Screenshot 1: window "stuck" to the top left corner of the screen. No borders, unresizeable.

Screenshot 2: Firefox tray icon acts as if Firefox was closed -- e.g. can't right click on it to close Firefox.

All help is greatly appreciated! Please let me know if I can further explain the issue in any way.

Are you using both LightDM and SDDM ? Is kwin installed or do you use a different WM ?
Have you tried to remove the files and folders from ~/.cache in your home directory and reboot the system ?
Are you on some sort of wayland session started from LightDM ?
Also, consider this:

Hi bogdancovaciu, thanks so much for your reply.

I (foolishly) realized SDDM was still enabled, so I ran:

sudo systemctl disable sddm
sudo systemctl enable lightdm

Upon reboot the windows are now properly manageable under LightDM.

I still don't know what the problem was with SDDM and haven't encountered anyone with a similar problem, however.

I think I might need to do a fresh KDE install to get SDDM working again.

To answer you: kwin is installed.

Hi Coraline. I'm having the exact same problem with two different computers running Manjaro KDE.
Both use NVIDIA graphics cards, so I have tried turning compositing off and switching to the Nouveau driver without change.
I'm away from home for a few days, but will try this solution on returning. I haven't made any modifications to the display manager, so have running whatever came in the standard install...
Let me know if yours stays fixed with your change to LightDM

Hi! Both happy and sad to see I'm not alone.

I'm able to USE Manjaro KDE with LightDM but the interface is completely different. Make sure to remember any configuration you've applied to SDDM before making the switch, as you'll wipe your .cache files.

I dislike the interface and will attempt to get SDDM working again.

Have you also tried logging into a new user? In my case, it didn't work -- the problem persisted -- but perhaps it could work in your case. Let me know.

Thanks for the commiserations. :slight_smile:
I found a solution...
It turns out that I had installed kwin-lowlatency from AUR at some stage, so all I had to do was install kwin (run in terminal) and this removed kwin-lowlatency and fixed the problem.
Hooray! Hope it works for you...

@mondocello finally got around to tweaking my Manjaro KDE PC and this worked! Thank you so much.

To anyone who stumbles upon this issue, I:

Updated KDE via the usual sudo pacman -Syu; rebooted to ensure nothing else was broken.

Then ran, as mondocello suggested, sudo pacman -S kwin to install kwin; when prompted to substitute "kwin-lowlatency," accept. Reboot.

Since I had substituted sddm with lightdm, I reverted that by running:

sudo systemctl disable lightdm
sudo systemctl enable sddm

Finally, rebooted. All my customization options previously applied to konsole, etc., were kept.
