1173971 - Consider setting GDK_CORE_DEVICE_EVENTS on test infrastructure for GTK3

Status: RESOLVED FIXED

(Core :: Widget: Gtk, defect)

Description

[Andrew Comminos [:acomminos]]

The focus issues with XInput2 and GTK3 detailed in bug 1170342 cause hangs with automated testing; for now, it may be best to force legacy Xlib events on the test infrastructure and make a plan to remove it in the future.

I think it makes sense to do this temporarily to improve our test coverage.

Attachment: Force core Xlib events on GTK3.

This patch sets GDK_CORE_DEVICE_EVENTS for all mochitests on GTK3. It results in a notable improvement of bustage on try (https://treeherder.mozilla.org/#/jobs?repo=try&revision=5a31afa27686, a few other patches included).

Whoops, that was a GTK2 try push.

Actual GTK3 push: https://treeherder.mozilla.org/#/jobs?repo=try&revision=ffaf884b9c8c
