(Core :: DOM: Events, defect)

Description

[Chris Peterson [:cpeterson]]

Steps to reproduce:

1. Run a debug GeckoViewExample (or Fenix) build in the Android emulator.
2. Load the following Samsung page: https://www.samsung.com.cn/smartphones/galaxy-s23-ultra/
3. Scroll up and down the page using swipe gestures. I'm using the touchpad scroll gestures on my MacBook.
4. GeckoViewExample crashes with the following assertion failure in adb logcat:

MOZ_Assert: [5479] Assertion failure: !aTime->mTimeStamp.IsNull(), at obj-aarch64-unknown-linux-android/dist/include/mozilla/BasicEvents.h:421

Note that I also hit APZ assertion failure bug 1852854 on this same page, so I had to comment out that bug's MOZ_ASSERT_UNREACHABLE.

Do you have stack trace when you hit the assertion failure? It's a bug of the creator of the instance.

I'm no longer able to reproduce this assertion failure. I don't know if our code changed or the site changed. I'll close this bug as WFM for now.
