879624 - Un-blocklist RDP for layers and WebGL acceleration

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

I just spun up a non-GPU AWS instance running Windows Server 2012 (m3.xlarge).  I'm connecting via RDP from my Windows 8 desktop.  If I force-enable layers and webgl, I get D3D9 accelerated windows, and WebGL is running fine -- 1.0.1 test suite passes, and Epic Citadel starts and runs fine at around 15fps.

I don't know how this works in RDP; is it chaining to my local D3D?  Either way, we should consider un-blocklisting this, maybe only with a new-enough Windows?

The support info:

WebGL Renderer: Google Inc. -- ANGLE (Microsoft Basic Render Driver Direct3D9Ex vs_3_0 ps_3_0)

Is this the software renderer?  If so, good enough for me, maybe even better than actual hardware!

Ah, if I force D2D I get D2D, DirectWrite, and D3D10 layers.  All seems to work fine.

Graphics
--------

Adapter Description: RDPUDD Chained DD
Adapter Drivers: RDPUDD
Adapter RAM: Unknown
Device ID: 0x0000
Direct2D Enabled: Blocked for your graphics card because of unresolved driver issues.
DirectWrite Enabled: false (6.2.9200.16433)
GPU #2 Active: false
GPU Accelerated Windows: 0/1 Basic Blocked for your graphics card because of unresolved driver issues.
Vendor ID: 0x0000
WebGL Renderer: Blocked for your graphics card because of unresolved driver issues.
windowLayerManagerRemote: false
AzureCanvasBackend: skia
AzureContentBackend: none
AzureFallbackCanvasBackend: cairo

We likely want to unblock this only on Server 2012.  That's probably a minor use case, but helpful for us.

Attachment: un-blocklist rdp >= 6.2

I think this is right?  It works for un-blocklisting, at least.

I don't expect that we use the mDriverDate anywhere, so you can probably skip it?

Kept the date thing, mainly because it was less work than removing it.

With Firfox 35.0.1 and RDPUDD Chained DD  acceleration is still disabled.
But if I force enable layers, webdl, directwrite it seems to be working fine.
Can someone check this and remove this blacklist if it is possible?
