Blank white screen

[zamazan4ik]

Hi!

For a while, I'm getting just a blank white screen when I launch Microsoft Teams from a flatpak instead of usual login screen. Screenshot:

In command-line, when I run flatpak run co.microsoft.Teams, I get the following:

My environment: OS: Fedora 34 Flatpak: 1.10.2 Microsoft Teams: the latest published in Flathub

If you need any additional information - just ping me and I'll try to help

Have the exact same problem on manjaro, but not using flatpak, istalled it from the AUR: Manjaro-Version: 21.2.4 Teams: 1.4.00.26453-1

Similar problem. The app is either invisible or just blank window. As I later figured out, it's not just Flatpak. Fedora uses Wayland by default, switching to X11 helps.

[meissnol]

I use X11 all the time. For me it helped to switch from the AUR package to the flatpak...

I'm using rhel 8 with flatpak and having the same problem.

I am on fedora 37 and this happens both with flathub and with the official RPM version. Doing flatpak run com.microsoft.Teams displays error message that canberra-gtk-module and pk-gtk-module are missing. So to me it looks like the base Teams package is missing some required parameter which is letting it not detect these libraries since both of them already exist in Fedora 37.
