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.

M.Hoogenboom 11 Reputation points2020-04-28T10:21:58.21+00:00 I've got the same issue with Fedora 31. Hope there will be a fix soon, because it is very annoying to have to quit Teams several times a day.

2020-05-06T15:19:05.337+00:00 Just a quick update. I noticed several folks were able to dig into the issue more thoroughly and some suggested the problem only occurs after you have a video call where you share your screen. I can now confirm that this is the case for me (at least on Ubuntu 20.04). If I have a video call where I don't share my screen, the CPU usage does not spike and after the video call is completed the CPU usage is normal. As soon as I initiate screen-sharing during the video call I have the high CPU usage that continues after the call is completed. Hopefully this helps the Microsoft engineers solve the problem.

Ted Gifford 11 Reputation points2020-05-13T16:16:28.39+00:00 The problem also occurs for me after sharing video, not just after sharing my screen. I'm not sure if either is actually a requirement, though. Interestingly, after I sent SIGINT the process restarted itself, so one might consider a terrible workaround. I'll just keep restarting manually, though.
I get the same results from strace of the spinning thread:
openat(AT_FDCWD, "/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor", O_RDONLY) = 39
read(39, "powersave\n", 128) = 10
read(39, "", 118) = 0
close(39) = 0
write(48, "\0", 1) = 1

JeffersonX 1 Reputation point2020-07-10T12:59:28.107+00:00 After the latest Teams update (1.3.00.16851) the issue doesn't occur anymore. I've working at home for a few months and I've been calling many coworkers without problems. The only thing I've noticed is the microphone icon on Gnome bar stills even though call finished.

sekhemrekhutawysobekhotep 46 Reputation points2021-08-09T16:53:07.28+00:00 Teams will use 100% CPU forever even when I just launch Teams and do nothing ... often Teams runs OK for a few hours then spontaneously goes into using 100% CPU when I am not interacting with Teams at all
this bug happens about once or twice every week before I bounce Teams then its OK
ubuntu 20.04 or any version of Ubuntu
in above comments MS person said over a year ago they are adding better error logging to Teams
... did that happen yet ?currently my Teams is version You have Microsoft Teams Version 1.4.00.13653 (64-bit).
Note this bug has been happening ever since I started using Teams on a linux laptop ... it happens on all my linux laptops so its not specific to some bad install of Teams ... and yes I have purged Teams and reinstalled to no help
Please fix.
