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.

We are currently trying to get better logging around this area, so we can better understand where the issue is. Please bear with us, we are trying to solve this out.
或许是缓存文件在视频通话结束时，未正常关闭结束运行，导致的因素可能有该版本Teams的系统兼容性问题，或者是bug。建议升级Teams到最新版本并卸载旧版本，同时保持Windows持续更新到最新版本，最后重启电脑。🐱👤

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.
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.

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:

efrain from using unnecessary formatting or bad language and be respectful of others in the community. Typing questions and comments in all caps and using unnecessary punctuation (!!1! / ???) will not increase the likelihood of your question being answered.

I can confirm this is an issue on Ubuntu 19.10 - one core gets spiked at 100% after a video call is terminated.
If this does not happen on 18.04, it is reasonable to assume that something changed in the runtime from 18.04 to 19.10.

I have the same problem with both, skype and teams.
Running Ubuntu 19.10 on an Elitebook 840 G3 with i5-6200U CPU, 24GB RAM and an NVME SSD.

I did a test in my environment (Ubuntu16.04 and Ubuntu 18.04) and it is no problem. After completing a video call, the CPU usage will reduce. You can try to solve this problem by clearing the cache folder.
I did try clearing out the cache, but the problem persists.
Based on the other comment below, it appears to be an issue with Ubuntu 19.10. I would be happy to provide additional details to Microsoft to help resolve the issue.
