Based on your description, it looks as if there is an incompatibility issue between new Teams and MSI.
There are a few possible solutions that you can try:
- Check and update if the Microsoft Teams is the latest version.
- Disable GPU hardware acceleration in Teams settings. Teams -> Click on your profile photo -> Settings -> Enable “Disable GPU hardware acceleration “. Then quit Teams from the taskbar and restart it.
- Clear the Teams cache from your device.
- If you’re using the Teams desktop or mobile app, try using the web version: https://teams.microsoft.com/.
Otherwise, New Teams currently has a few features that aren't perfect, and as an alternative solution you can switch back to old Teams if you need to.
