Description: When typing a reply to an existing conversation thread, and another thread is created or replied to, Teams shifts focus out of the "reply" dialog and scrolls the window to the latest conversation thread. The user must then scroll back up and click reply again to continue typing their response.

Reproduction Steps: Start a conversation thread in a channel. Begin to reply to the thread. Have another user start a new conversation thread in the same channel. Your reply will lose text-box focus and the window will scroll up to show the new thread which will be given focus. You must click back on reply to the previous thread to continue typing.

Despite having a good WiFi or Ethernet connection, regardless of which network I'm on, if I join a Microsoft Teams call, all network connectivity stops working and teams simultaneously reports poor call quality and no network connectivity. All this while on an active call which I can see and hear. Here's a full description of symptoms.

Every time I connect to a Teams meeting:

• Incoming call quality is ok. I can hear and see others.


• Outgoing call quality is very poor. Others say my voice is breaking up.


• If I unmute and speak for more than a few seconds, I am booted from the call.


• If I stay muted I can stay on the call indefinitely.
  I can share my screen just fine, I don't get kicked from the call.


• Teams periodically puts up a warning symbol in the call controls reporting poor connectivity.


• Teams puts up a blue banner stating that I have been disconnected from the internet.
  (Intermittent) Teams puts up a big overlay on top of the whole app saying I have been disconnected


• The call continues though all of this, including voice and video.


• All other network connectivity is broken (e.g.: Browsers cannot load pages, network drives stop working)


• Text chat features work fine outside calls but not during calls, where they fail to work like all other network activity)


• The instant the meeting ends, all the symptoms stop. I can access network resources again.

My wifi connection is fine. I've tested using wired networking and encounter the exact same issue. I've also tried various audio devices and disconnecting all peripherals as longshot solutions. No dice. I don't have anything weird on my system as far as I am aware. Teams works fine on other machines but not on my primary laptop.
This issue not only makes Microsoft Teams itself nearly unusable, it knocks my whole system offline for the duration of the call, which is incredibly frustrating.

I'm booting into Windows 10 on a 2015 MacBook Pro 13". I have all the latest patches for everything. Teams Version 1.2.00.26774 (64-bit)

I've tried clearing the %appdata%\Microsoft\teams folder. I found no change to the issues I am having. After joining a meeting I was greeted with a "No internet connectivity" banner and a warning symbol in my call controls panel.

I ran the Skype for Business Network Assessment Tool. It found no issues:

C:\Program Files (x86)\Microsoft Skype for Business Network Assessment Tool>networkassessmenttool.exe /connectivitycheck
Skype for Business - Network Assessment Tool

Starting Connectivity checks
Verifications completed successfully

Web client works fine. No issues with network connectivity. I was able to place a call no problem.

I've seen two other people who have what I think is the same issue as mine, but their question threads didn't have any solutions, and now they're locked.

Does anyone have any idea what could be going wrong? Any solutions? Any more info needed from me about my setup?

Since about 1-2 weeks before Christmas 2020, on any MS Teams call my video is presented to other participants either in black and white or with weird graphical artifacts (colored shadows over the video), while my preview looks completely normal.

Based on reddit thread and MS Teams forum discussion (see links below) I am not the only one experiencing this; also based on the discussion my first guess would be a relation to nVidia GPU and GPU drivers (I have a GTX 1070 GPU with latest drivers, Logitech Brio web cam).

Example screen shot of a shared Teams window (including my own video preview in color as well as what others saw in black and white) attached.
