Created attachment 628213 [details] [diff] [review] Only check for D3D 10.0 support when selecting a DXGI 1.1 adapter In order to properly create textures that can do synchronization we need a DXGI 1.1 adapter to be used for device creation. This can be done on all updated Windows 7 and Vista, and we currently try this. However if the device does not support D3D 10.1 we wrongly toss out the adapter and create the device with a NULL adapter. This is wrong and prevents DXGI async drawing from working on DX10 machines.
Created attachment 628214 [details] [diff] [review] Only check for D3D 10.0 support when selecting a DXGI 1.1 adapter v2 Updated: It's probably a better idea to fail D2D acceleration all together if this weird situation should occur where we can somehow get a D3D10.0 device without DXGI 1.1 support.
Please can you set the milestone when landing. Thanks :-) https://hg.mozilla.org/mozilla-central/rev/3187b6d743db
