Comment 2

[Brad Werth [:bradwerth]]

I'll sort this out.

Comment 3

[Brad Werth [:bradwerth]]

Can't replicate. It's possible this is an Out of Memory situation resolved by the patch for Bug 1732230. I'll keep this open to see if it is disappears after that patch lands.

Comment 4

[Brad Werth [:bradwerth]]

The crash signature doesn't make this very clear, but the crash occurs when we attempt to return mFrontSurface to the pool. I'll see if we can add some more tracking or asserts around the handling of mFrontSurface to catch this problem earlier.

Comment 10

[Brad Werth [:bradwerth]]

This may have been fixed by Bug 1736446. Whether or not that is the case, that Bug reveals that NativeLayerRootCA needs to be made resilient to concurrent access. There's more we can do to improve access and I'll do that in a patch for this Bug.

Comment 11

[Brad Werth [:bradwerth]]

Attachment: Bug 1731956: Make NativeLayerRootCA fullscreen and mouse move accessors thread safe.

In addition to adding locks around the accessors, this also removes the call
to CommitToScreen from the fullscreen accessor, which was probably
redundant and definitely made the main thread call Commit which introduces
possible concurrency errors.
