Bug 196150

Summary:	WK1 compositing/plugin tests always fail on my machine

Description Simon Fraser (smfr) 2019-03-22 08:53:02 PDT

On my machine these tests WK1 plugin tests:

compositing/plugins/composited-plugin.html
compositing/plugins/no-backing-store.html
compositing/plugins/small-to-large-composited-plugin.html

always behave as if there is no plug-in, yet the tests pass on bots.

Why the difference? Is there some plug-in installation or policy setting that run-webkit-tests is failing to control on user machines?

Probably! I do not know what it is, despite having looked into what machine specific things can still affect tests before.
