Attachment: Screenshot of issue

Seen while running  Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:10.0) Gecko/20100101 Firefox/10.0

STR:
1. Run the lights demo
2. Observe the artifacts in the attached screenshot.

I don't think they are supposed to be there since they don't ever seem to move, and they crop in different places while I am

I haven't been able to reproduce this on nightly yet, but will try tomorrow.

Unable to reproduce with Firefox 10.0b2 on Mac OSX 10.6.8 on a Macbook Pro 7,1.
Here is my about:support::Graphics:

Vendor: ID10de
Device: ID08a0
WebGL Renderer: NVIDIA Corporation -- NVIDIA GeForce 320M OpenGL Engine -- 2.1 NVIDIA-1.6.36GPU 
Accelerated Windows: 1/1 OpenGL

We need to track down what specific hardware this is reproducible on and find a possible regression range.

WebGL Renderer NVIDIA Corporation -- NVIDIA GeForce 9400 OpenGL Engine -- 2.1 NVIDIA-7.4.10GPU 
Accelerated Windows 1/1 OpenGL

Any luck trying to track down a definitive environment / regression window?

Comment 6

[Kelsey Gilbert [:jgilbert]]

I also can't reproduce on my MBP:
Device ID	0x 863
GPU Accelerated Windows	1/1 OpenGL (OMTC)
Vendor ID	0x10de
WebGL Renderer	NVIDIA Corporation -- NVIDIA GeForce 9400M OpenGL Engine

Marking WFM.
Please reopen if you have hardware/drivers which still reproduce this issue.
