Screen turns black or Thinkpad reboots when sharing desktop in MS Teams
When sharing a desktop with MS Teams, no matter whether it's the full screen or just an application windows, in about 50% of the cases the screen turns black for the user sharing the screen and all viewers. Seldomly, the Thinkpad E15 Gen 3 crashes to the Bios start screen. More frequently (up to ~50% of all sessions), the screen turns black for about 15 seconds, but eventually recovers. Sharing again sometimes works, sometimes the issue repeats. Restarting MS Teams usually does NOT help, but after a random number of attempts and having wasted 5-10 minutes of a meeting, it eventually works.
This happens with no dock or external monitor attached, but occurs also with a dock and two secondary monitors attached.
This is a 20YGCTO1WW (AMD Ryzen 7) with BIOS R1OET35W 1.14 and Radeon driver 21.40.64.06-220708a-381956C-Lenovo
Neither Windows nor Lenovo Vantage does find any new drivers / updates; Windows 11 Business 22H2, Build 22621.1848.
Any idea on how to solve this problem? We're a software company and not being able to share a screen without failure is just plain embarrassing. Didn't have the same issue with any other software or Zoom for that matter.
Any ideas how to fix this?
