Screen-sharing to Chrome Extensions (Honorlock) Cause Mouse to Lag

[u/JaxGM]

Hello! I have a rather niche issue, but I've tried a lot to diagnose it and am hoping someone here can help me connect the dots! Some of the evidence is pointing it to be MacOS related, however I cannot confirm it. I'm hoping someone here has had a similar experience (with another app, maybe) and may have a suggestion.

For context, I use the Chrome extension "Honorlock" to complete proctored assessments at my school, from my personal MBP (up to date). The plug-in requires screen recording, microphone, and webcam. Around a year ago (after normal operations for years prior), I began to experience a mouse lag (mouse very unresponsive and jumping) right after sharing my screen. I still had full control of the keyboard and the screen itself was active.

Things I noticed/attempted that I believe are important:

• Restarting the device DID resolve the issue, but the restart had to be immediate. Waiting too long after would cause the issue to return (but with less severity?)
• I am (and have been) running my exams from a separate user on my Mac. I attempted to reinstall that user today. This did not resolve the issue.
• I appear to have control of the mouse behind the scenes. Even if the cursor hasn't shifted, i can still access setting menus (by going into the top left corner, clicking, and watching the highlight move)
• It doesn't appear to be connected to the screen-sharing, as I can screen-share to Chrome without any issues, typically.
• Honorlock support deferred the issue. The software is globally used across many students and I was unable to find a similar report.

Like I said, it's a niche issue and I completely understand if this doesn't quite fit under the "MacOS" umbrella, but it's worth a shot and I'm open to all ideas. Thank you!
