1819807 - NVidia PRIME offloading does not support 32bit EGL contexts

Status: UNCONFIRMED

(Core :: Graphics: WebRender, defect)

Description

[Ashley]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/110.0

Steps to reproduce:

On a laptop with Intel Integrated graphics, and NVidia RTX A1000 card. With latest Mesa upstream Intel drivers, and latest proprietary NVidia v525 drivers.

Intel integrated graphics is set up as Primary GPU, and NVidia card is offload GPU.

OS: Ubuntu 22.04

Running Firefox v110.0.1 in EGL mode with NVidia Prime:
~> __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia MOZ_X11_EGL=1 firefox
"[GFX1-]: Failed to create EGLSurface!: 0x3009",
"[GFX1-]: Failed to create EGLSurface. 1 renderers, 0 active.",
"[GFX1-]: Handling webrender error 3",
"[GFX1-]: Fallback WR to SW-WR"

Actual results:

~> __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia MOZ_X11_EGL=1 firefox
MOZ_X11_EGL=1 firefox
"[GFX1-]: Failed to create EGLSurface!: 0x3009",
"[GFX1-]: Failed to create EGLSurface. 1 renderers, 0 active.",
"[GFX1-]: Handling webrender error 3",
"[GFX1-]: Fallback WR to SW-WR"

Exactly the same issue can be seen in the last couple of comments in this related bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1739611

Reproducing the same issue using GLMark2-ES2
~> _NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glmark2-es2
Error: eglCreateWindowSurface failed with error: 0x3009
Error: eglCreateWindowSurface failed with error: 0x3009
Error: CanvasGeneric: Invalid EGL state
Error: main: Could not initialize canvas

Works fine on the integrated graphics:
~> _NV_PRIME_RENDER_OFFLOAD=0 glmark2-es2

glmark2 2021.02

After doing some research I found the same issue was observed in OBS, and they fixed it by switching to 24bit (no alpha channel) EGL context. https://github.com/obsproject/obs-studio/issues/6984

This is confirmed by checking available buffer configs when using PRIME:

Only 24bit contexts are available.

Finally, testing witth GLMark2-ES2 when disabling the Alpha Channel, it works:

~> __NV_PRIME_RENDER_OFFLOAD=1 glmark2-es2 --visual-config red=8:green=8:blue=8:alpha=0:buffer=1

working

Expected results:

I expect if Firefox can request a 24bit EGL context in Prime offloading situations, then it will solve this issue.

Sorry about the formatting, seems the submission form didn't like my markdown. It seems to format differently than the comment dialogs.

Comment 2

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for the report!
How does Firefox behave if you start it with your env vars and MOZ_ENABLE_WAYLAND=1 on Wayland?
$ __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia MOZ_ENABLE_WAYLAND=1 path/to/firefox

PRIME render offload is the ability to have an X screen rendered by one GPU, but choose certain applications within that X screen to be rendered on a different GPU.

Running Firefox v110.0.1 in EGL mode with NVidia Prime:
~> __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia MOZ_X11_EGL=1 firefox
"[GFX1-]: Failed to create EGLSurface!: 0x3009",
"[GFX1-]: Failed to create EGLSurface. 1 renderers, 0 active.",
"[GFX1-]: Handling webrender error 3",
"[GFX1-]: Fallback WR to SW-WR"

Copying between two GPUs is not more performant as using the primary GPU with Dmabuf WebGL etc.
0x3009 is EGL_BAD_MATCH. The driver does not support transparent OpenGL windows.
Firefox' window and its toolbar panels have round corners, therefore they need transparency. You get Software WebRender as expected.

Hi, I just wanted to add that I am having the same error and general behaviour as OP.
I cannot test under wayland, as I am running Debian and wayland is disabled when using the proprietary NVIDIA

If it is indeed only due to the transparency, wouldn't it make sense to be able to disable such a non-essential feature if it meant enabling HW acceleration support in many more cases ?

Thank you
