If this crash was recently introduced then it may be related to recent refactorings. Adding a couple more components and CC'ing people more familiar with Viz and GpuMemoryBuffers.

Still seeing this flake, e.g.[1]. Fady can you triage/assign?

Passing along to backer@ who might be more familiar with this.

Comment 5 by backer@chromium.org, Nov 14 

Glancing at the output, this is probably OneCopyRasterBufferProvider triggered. We've got CopySubTextureCHROMIUM and GpuMemoryBuffers in the log spew and that class uses both of them.

A lot of that has changed with the SharedImage refactoring that is going on. Does this still repro as of https://chromium.googlesource.com/chromium/src/+/9058f7866e74b92eeef1c30780522fba0740d2f3 ?

Status: Closed (was: Available)
Thanks noel@. I'm going to close this as obsolete for now. Please feel free to reopen and assign to me if this becomes and issue again.
