High CPU Usage Continues after Ending Video Call

Question

Edit 2: I'm running the latest teams-insiders build (1.3.00.16851) which was released June 17, 2020 and the problem seems to have gone away. I've been on several video calls today - which all included screen sharing and the CPU usage has returned to normal afterwards! Hopefully these fixes get incorporated into the non "insiders" builds.

Edit: the problem (for me) only occurs on a call after I share my screen. If I am just using my camera the CPU usage remains normal. Hopefully this helps troubleshoot the issue.
Update: I was mistaken, problem still exists.

Hello All,

I've noticed after completing a video call in Teams that the CPU usage remains high. The only way to get the CPU usage to return to normal is to close Teams completely, and then reopen it again.

I'm running on Ubuntu 20.04.

If I had to guess the process that's spawned for the video call is never terminated, despite the call ending.

Answer 1

A lot of users are complaining about the same problems, both with Ubuntu 19.10 and Mint 19.2. This is a known issue and doesn't seem to be anything specifically wrong with your machine.

Some users have had luck by clearing the cache folder:

rm -rf ~/.config/skypeforlinux/Cache/*

The only other way at the moment is to shut off Skype from within the "top" command from the terminal.

I know this doesn't solve your problem, but until the Linux distro is updated, it doesn't seem that there is a solid fix just yet. Sorry!

Hi,
The same issue is bugging me on openSuSE Leap 15.1 . The teams version is 1.3.00.958 (64-bit).
Will try to clear the cache.

On mint 19.3 here; videocalls/screensharing or just plain meetings makes the kernel go bananas, there's a kworker-thread eating all CPU and making my wireless crawl to a halt disconnecting me from meetings and ruining the call quality.
I've gone back to a electron wrapper, sadly.

It looks like this a problem with Skype for Linux more generally.

i also can confirm this "teams" problem on ubuntu 19.10 with lenovo t490.
On my machine there is nothing like ls -l ~/.config/skypeforlinux/Cache/
