1271554 - Float texture framebuffer attachments will not work without WEBGL_color_buffer_float in WebGL 2.0

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20160503030421

Steps to reproduce:

1. Use a version of Firefox which supports WebGL 2.0
2. Visit http://jsfiddle.net/ncsdcdvu/4/
3. Open JavaScript console
4. See output "status is 36053. Expected value: 36053"
5. Comment out the line "gl.getExtension("WEBGL_color_buffer_float");"
6. Hit Play
7. See output "status is 36054. Expected value: 36053"


Actual results:

When disabling the WEBGL_color_buffer_float extension, we cannot attach a RGBA32F texture to a framebuffer (checkFramebufferStatus will not return FRAMEBUFFER_COMPLETE).


Expected results:

In WebGL 2.0, EXT_color_buffer_float should be the only extension required to enable rendering to RGBA32F textures.

Hi Jonas,

I have tested this issue on Mac OS X 10.10 with FF Nightly 49.0a1 with new profile and I can't reproduce the issue, after step 6 my output is: "status is 36053. Expected value: 36053" Can you please retry with the latest Nightly version?

I believe that Jeff Gilbert has landed a fix for this last week.

After updating my Nightly from one from earlier this month to today's, I can confirm that the issue is fixed now.

Thanks for your feedback, based on commnet 2, I will mark this as Resolved WFM, feel free to reopen it if you encounter the same issue on latest FF version.
