Try one of the following approaches:
- Disable GPU Acceleration via the json config file found in %APPDATA%\Microsoft\Teams\desktop-config.json (i.e. C:\users<username>\Roaming\Microsoft\Teams\desktop-config.json)

- If that doesn't work, revert that change and then disable Image Scaling via your Graphics Driver Settings
