There are three status values: "unknown", "rendering", and "failed".  Do we really want to destroy the layers every time the status changes?
Comment 4 youenn fablet 2021-08-05 09:52:15 PDT 
Good point, we should rename it to sampleBufferDisplayLayerStatusFailed.
Comment 5 youenn fablet 2021-08-05 09:52:30 PDT 
And only call it when rendering fails.

No, bug 228759 is due to an unrelated regression
