Screen share “Portal” window not clickable (Wayland/KDE Plasma)

Hi, i’m trying to screen share in Teams (running in Firefox)

  • Wayland

  • KDE Plasma 6.6.5

  • Fedora 43

When I click the Share screen button in Teams, a new window named “Portal” appears. However, when I try to click or focus it, nothing happens.

The window does not appear in the Alt+Tab switcher on any desktop or screen. If I press Meta+W(Overview), I can see the Portal window again, but I still can’t interact with it.

Right clicking the Portal window in Overview pins it and makes it appear in Alt+Tab, but it remains unfocusable and cannot be interacted with.

I have also tried the options under the “More” submenu, like “Fullscreen”, “Keep Above Others” when right-clicking the window, but none of them fixes it.

Has anyone experienced this before, or am I missing something obvious? It may be related to Firefox rather than KDE.
