Can no longer share individual application windows in browsers

Until sometime early December I was able to share individual application windows as well as my entire screen. Then I did not need that feature for some weeks during which there were a few updates and I briefly tried out kwinft. But I went back to kwin since I suspected kwinft to be the cause for external monitors when plugged in to not be configured correctly. After reverting to kwin external monitors are always correctly configured, but I still have the issue that e.g. in Teams I can only share the entire screen and not individual application windows.

Grateful for any suggestion you might have,


Might be Wayland instead of X11. Choose X11 in the login screen and try again.

Hey, I’m so old-school I didn’t even mention that this WAS on X11…

I can’t remember if Teams was ever able to share individual windows. Are you 100% certain?

Does this happen for all other applications as well? E.g. test with Zoom.

It definitely was working even on Teams and it happens everywhere even on the gUM test page.

What is a gUM test page?

Also, I tested OBS and while it “sees” the windows when I select one the area where it’s supposed to appear remains black.

Can you put your system information here?

I did play with some systemctl status commands and here is a message that caught my attention:

Feb 13 09:32:17 allofthis xdg-desktop-portal-kde[1513]: xdp-kde-settings: Namespace "org.gnome.desktop.a11y.interface" is not supported

Also, I noticed that my original statement was not entirely correct: in Chrome as well as in Firefox I can share one window and that is the window of the browser itself. So, when on gUM Test Page with Chrome I can share the entire screen or I can share any of the Chrome windows and when in Firefox I can share the screen or any of the Firefox windows. But none of the other windows show up.

Could this be a pipewire permissions issue? Where would I look to investigate whether or not it is?

Today, by chance I had another window open ON THE SAME virtual desktop an which the browser was running when I started sharing. To my surprise that window was available for sharing in the selector. Other windows remain unavailable there.
