commit 7813cebd9f79de65d16e262ce79b675e7ec132c3 Author: Lee Salzman <lsalzman@mozilla.com> Date: Thu Sep 26 02:31:15 2019 +0000 Bug 1578075 - Increase stack size of paint threads on macOS Catalina to 2MB. r=jrmuizel Still getting some crash reports on nightly with a 1MB stack. Let's try one more time with 2MB just to see if we can eliminate those. If this fails, then we may need to consider more drastic approaches like disabling OMTP in this case.
