After talking to csharrison@, here are some updates: Issue can be reproduced in Chrome (Dev) 72.0.3590.0. It can not be reproduced in Chrome (Beta) 71.0.3578.20. No flags have been enabled.

+enne@ as it sounds like a compositing issue where the page no longer composites correctly when the video is drawn with a surfacelayer.

If somebody has time, it might be worth doing a bisect to see what broke this. Hmm. This doesn't appear to happen on Linux with those same flags. Sending this to ccameron to triage this mac issue. I'm not sure why the entire page stays blank when switching tabs in this case.

I think a bisect would blame ... r601409, especially if the window re-appears when it gets resized.

Is this a matter of simply reverting https://chromium-review.googlesource.com/c/chromium/src/+/1292377 or do you have a fix in mind already?
,
Oct 31
I've seen other problems around that time. It should be simple to debug, just a matter of finding the time.

How can I help debug this?

The most reliable repro that I have of this is to do (3-dot menu) -> cast, then switch tabs, then switch back. - this doesn't happen with the self-mirroring extension - and my local build doesn't find the cast devices on my network (grumble) PiP is working for me, but I'm sure that whatever the issue is, it affects everything equally. So I'll keep poking with a stick until this works.

This does happen (every time!) with the tabCapture extension enabled. But not on local builds. I'm trying a release build w/o DCHECKs to see if that changes anything.
,
Nov 2
Tried a release build w/o DCHECKs, and no repro. Revert has merge conflicts. Sadness all around :(

Finally I managed to force this to reproduce by explicitly calling delegated_frame_host_->ClearDelegatedFrame(). Should be easy enough to fix now.

Management of surface ids in BrowserCompositorMac has managed to bit-rot to the point that I can't follow the logic in the file anymore. We need to be VERY rigorous when it comes to reviewing changes to these files, because they can become incomprehensible very quickly.

RenderWidgetHostViewMac no longer participates in CATransationObserver (except for native embedders like ContentShell, which will now have non-smooth resize).

Okay, I can repro this anywhere now. The trick is that you need several windows to be open at the same time. What happens is that in TransitionToState when going from backgrounded to foregrounded for a casting tab - we start with our own compositor - because we're not attached to a browser, but casting - we destroy it - when it is destroyed, because we have many windows open, we evict the frame - this increments our surface id - then we attach to the browser, and call EmbedSurface using the new surface id We never send the new surface id to the renderer. So the bug is that BrowserCompositorMac::WasEvicted at [0] needs to send that new surface id to the renderer (at some point).

Inline the optional-argument-not-passed version of this function at its only callsite, RenderWidgetHostViewMac:: EnsureSurfaceSynchronizedForLayoutTest. - Rename BrowserCompositorMac::SynchronizeVisualProperties to UpdateSizeFromChild Bug: 897156 Change-Id: Ib01aae5c0ef4e92298697c1840da7bc6e8cbf3a0 Reviewed-on: https://chromium-review.googlesource.com/c/1316678 Commit-Queue: ccameron <ccameron@chromium.org> Reviewed-by: Fady Samuel <fsamuel@chromium.org> Cr-Commit-Position: refs/heads/master@{#605865} [modify] https://crrev.com/cab2f4ed8d3b66977115ee387aee0450bb3f1aeb/content/browser/renderer_host/browser_compositor_view_mac.h [modify] https://crrev.com/cab2f4ed8d3b66977115ee387aee0450bb3f1aeb/content/browser/renderer_host/browser_compositor_view_mac.mm [modify] https://crrev.com/cab2f4ed8d3b66977115ee387aee0450bb3f1aeb/content/browser/renderer_host/render_widget_host_view_mac.h [modify] https://crrev.com/cab2f4ed8d3b66977115ee387aee0450bb3f1aeb/content/browser/renderer_host/render_widget_host_view_mac.mm

The new version has 3 steps - detect no-op changes and early-out - detach from the current compositor, if there is one - attach to the new compositor, if there is one This allows the code the common code between the "parent ui layer" compositor and the "has attached compositor" state. Update the comments about the states to reflect the simpler reality. Fix a bug wherein transitioning between HasOwnCompositor and UseParentLayerCompositor would briefly hide the DelegatedFrameHost and allow the frame to be inappropriately evicted.

From a Picture-in-Picture perspective, this is fixed. Is there remaining work to address there?

Nope (apart from general cleanup which is a very far-back burner). |
