Bug 1789658 - Keep gl::SharedSurface/TextureData alive if remote texture's TextureHost is still in use by WebRender
48 bytes, text/x-phabricator-request
Details | Review

Testcase found while fuzzing mozilla-central rev 663615ef7a19 (built with: --enable-address-sanitizer --enable-fuzzing).

This is a recent regression. Due to the simple testcase, this issue has been seen hundreds of times in the past few hours. Marking as a fuzzblocker. Please prioritize accordingly.

Testcase can be reproduced using the following commands:

$ pip install fuzzfetch grizzly-framework
$ python -m fuzzfetch --build 663615ef7a19 --asan --fuzzing -n firefox
$ python -m grizzly.replay ./firefox/firefox testcase.html
