Is there a way to detect if a system is using the D2D1.0 backend? I'd like to schedule some AB testing once this lands in Nightly, assuming either Betabreakers or ourselves have access to qualifying systems.

Yeah, you can go to about:support. Under "AzureContentBackend", it should say "direct2d". If you'd like to force d2d 1.0 right now, you can go to about:config, change the preference "gfx.content.azure.backends" to "direct2d".

We have some telemetry data to this effect - http://people.mozilla.org/~danderson/moz-gfx-telemetry/www/#view=windows-features, Direct2D is currently hovering at around 10% of the nightly population.
We can practice it with preferences to start, but it shouldn't ride the trains quite yet.

My about:support shows "AzureCanvasBackend: direct2d 1.1". Will this bug affect a system like mine (ie. D2D1.1 systems) or does this just affect D2D1.0 systems?

It should only affect d2d 1.0 systems.

I think this is done. Closing as WFM.
