The attached graphic shows the behaviour of the CPU during the bug... while in a video call using the webcam, the CPU spikes (all cores at 100%) for a few seconds and then subsides. During that, the video that I'm sending is no longer viable with a lot of stops and starts and freezes, and I also can no longer understand the other participants on the call.
This seems directly connected to webcam usage. The problem does not happen when the webcam is off. (This obviously isn't a viable permanent solution.) It also isn't consistent... the CPU will spike for a few seconds and then go back to normal levels. The spike doesn't seem to be connected to anything I'm doing or not doing during the call. This feels like perhaps the CPU and the webcam are somehow buffering or packaging a lot of info at once? The program that is shown with the highest CPU usage is whatever program is using the webcam. Zoom, or the browser if it's a browser-based video meeting. ** Attachment added: "Graphic of the CPU spiking during a web call" https://bugs.launchpad.net/ubuntu/+bug/1929124/+attachment/5506553/+files/cpu%20spiking%20during%20web%20call%202.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1929124 Title: When using webcam, CPU spikes to 100% for a few seconds, then drops, then recurs minutes later.
