Looks like the webrtc code is making copies of a frame from this queue offthread. There's no stack for the main thread but my best guess is that we'd be looking at something similar on it. We may need to add a suppression for it.

If we only have occurrences where one stack is missing, then it is very likely that an existing suppression is interacting with this. What we need to figure out is if this is a dup to an existing issue or a new issue that doesn't show up properly because of an existing but unrelated suppression.

Kris, can you check existing suppressions around the code and see if you can reproduce this on try with the given test?

This particular bug behaves very oddly. I haven't been able to get an exact reproduction of this issue, so all I've been able to get is traces with PlatformThread calls in them when I remove the other webrtc suppressions. I'm wondering if those suppressions are interfering with the main thread stack, which may include some webrtc logging. I wonder if we should add an additional webrtc suppression for CaptureFrame. Based on what I can find on searchfox it appears that the queue of frames is not thread safe. If it's possible to turn off these logs then we might be able to get more details.
