Comment 25

[Kartikaya Gupta (email:[e-mail])]

I wasn't able to reproduce this locally (didn't try super-hard either) but just from looking at the test, it uses ad-hoc code to wait for the paints to be flushed. This predates all the newfangled things we have, and we should update the test to use the newfangled things that are more robust.

More specifically, I suspect what is happening here is that the test in helper_bug982141.html runs immediately after isMozAfterPaintPending gets cleared, and requests the compositor APZ test data. However with WR there is more chance that the transaction is still in-flight (stuck in the updater queue waiting for the scene build to happen, for instance) and so the compositor APZ test data query comes back empty. If we add a flushApzRepaints or something that does a round-trip through the updater thread that should fix this.

To stop this bug from getting starred more. If there are more failures they should go in a new bug.
