Microsoft Teams PWA - Background filters does not work

Ask Fedora Ask in English

Since the launch of Microsoft Team PWA, you have the options to blur your background or set a custom background in order to prevent the rest not to see your room. I realy liked this option as with the regular Teams for Linux did not include this option.

But since the last fedora update, this option does not work anymore. When trying to select a background filter, the application keeps loading untill I cancel the action. I took a glance at the logs and see something suspicious:

Generally I tried to use Teams PWA in combination with Microsoft Edge. I tried to switch browers and used chromium-freeworld from the rpm-fusion repo and google chrome as a flatpak, both without results.

I am running Fedora 37 and didn’t have any issues so far. As I need MS Teams for work, I would like to get the PWA running with all options working. Problems where arising after the last dnf upgrade I performed last weekend. Generally, I update only once a week.

make a
sudo dnf history
see the number of the last view actions and you can check them with
sudo dnf history info #number

So you can see what got changed and eventually you can make a downgrade of the specific app.

Hello ilikelinux,

Thank you for your reply. I examined the output of the dnf history info command and had to guess somehow which package I had to downgrade. Turns out is was the mesa-libEGL package. After this was downgraded, Teams was running as usual.

I updated my /etc/dnf/dnf.conf file whereby I added mesa-libEGL.x86_64 and mesa-libEGL.i686 as an exclusion. I am wondering if I need to fill in for a bugreport for this specific package and second, how long do I need this as an exclusion in my dnf.conf.

Again, thank you for your help.
