This is a regression from my changes. I'll investigate.

From a code inspection I didn't really see any reason this should be happening except maybe during shutdown scenarios. I also couldn't reproduce it locally, although it seems like it's not isolated to any one test but is just happening randomly.

Try push with some logging to try and narrow it down: shows that we're adding a new pipeline but updateDisplayList is coming out false at [1] in the transaction that it's added, so then we don't push a display list for it. Another try push is at [2] with more logging to drill down into why updateDisplayList is coming out false. But a reasonable fix might be to create a display list anyway the very first time, so that WR doesn't have to worry about the missing pipeline content.


Looks like the pipeline's mCurrentTexture is null, so we don't set the display list for the pipeline.

I'll file a new bug for this. It gets really confusing when bugs with patches landed are reopened without the patches getting backed out.

Actually, the log you linked to in comment 26 doesn't have the assertion in the title ("assertion failed: info.ignore_missing_pipeline") anywhere in the log. Are you sure you have the right link/bug?

Oh, I see. It matches bug 1438418 which was duped to this bug. But the root cause in the new failure looks different. I'll file a new bug for it.
