In the logs from mid January and before (Comment 20) the leaks are in test-linux64-asan/opt-test-verify-e10s, and have MediaPipelineReceiveVideo::PipelineListener::RenderVideoFrame in the stack. Starting in comment 21 from 02-11, the leaks are in test-linux64-asan/opt-mochitest-media-e10s-1, are more frequent, and have FFmpegVideoDecoder<55>::DoDecode in the stack. Those started on Feb 9. So maybe some new media thing landed around then?
"Texture deallocated too late during shutdown" also suggests something did try to free this memory. Maybe there was some change to media shutdown. The message is a little spammy, but I think that in the log from comment 24 that message is being triggered 8 times, and then we leak 8 textures.

Update: There have been 55 failures in the last week. Summary: Intermittent LeakSanitizer | leak at NewSegment, CreateSegment, mozilla::ipc::Shmem::Alloc, mozilla::ipc::IToplevelProtocol::CreateSharedMemory This fails only on Linux x64 / asan. Here is a recent relevant log file: https://treeherder.mozilla.org/logviewer.html#?repo=mozilla-central&job_id=167249478&lineNumber=3510
rillian, do you know who might be able to look at this? Thanks.

Jean-Yves, looks like there's a frame data leak in FFmpegVideoDecoder::DoDecode.

I don't see how this can be happening, and unfortunately, don't have the bandwidth to dive into it at this time

no failures on trunk since March 20th and only a few on mozilla-beta.
