Thanks Marcia, I'll be looking into this.

:bobowen, since this bug is a regression, could you fill (if possible) the regressed_by field?
For more information, please visit auto_nag documentation.

These nearly all appear to be either device resets or OOMs, with one invalid size.
Crashing is clearly too aggressive here.
I think it should:

• make sure the reset has been reported, if there is one
• probably add a critical note
• return null
• check for null in the callers and in the normal case add a null surface descriptor against the content DrawTarget pointer
• handle the null descriptor when retrieved on the Compositor thread

This should be fixed by patches in bug 1598585.
