Created attachment 8534554 [details] [diff] [review] Call UpdateImageContainer whenever we send invalidations in RasterImage Since debugging showed that the images involved here are getting decoded, notified about, etc. successfully, my next theory was that the layers::ImageContainer was falling out of sync. This proved to be correct, and the fix is extremely straightforward. I do feel like we're starting to get too much logic about invalidations in FinishedSomeDecoding; a future refactoring should try to clean this stuff up a little. At least it's the *only* place in RasterImage we have logic about invalidations due to decoding now.

Before that patch, I could reproduce the problem 75% of the time on a shift-reload. After the patch, I cannot reproduce it at all. That said, this bug is timing dependent, so I think we should ask QA for a verification of the fix. This also needs an uplift to Aurora. (And a try job, but try is closed right now.)

Created attachment 8534720 [details] [diff] [review] Call UpdateImageContainer whenever we send invalidations in RasterImage Thanks for the review! I made a minor tweak; now we only call UpdateImageContainer if the default decode flags are used. Doing it otherwise is pointless, since we use the default decode flags version of the image in UpdateImageContainer.

Comment on attachment 8534720 [details] [diff] [review] Call UpdateImageContainer whenever we send invalidations in RasterImage This needs an uplift to Aurora. I am very sorry to say that because the dependencies here are *massive*, we cannot uplift to 35, even though it's affected. =( I'll look into the possibility of making a different version of the patch that could land on 35. Approval Request Comment [Feature/regressing bug #]: 1069369 [User impact if declined]: Sometimes part of an image will be cut off. [Describe test coverage new/current, TBPL]: On m-c. Current tests should cover this; it's not clear to me right now why we're not getting intermittent oranges from this issue. (OTOH, there are several unexplained intermittent orange bugs in ImageLib right now, so maybe we are...) [Risks and why]: Low risk. We just update the version of the image displayed onscreen more often. [String/UUID change made/needed]: None.
