Attachment: Adnotacja 2020-08-12 100451.jpg

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:79.0) Gecko/20100101 Firefox/79.0

Steps to reproduce:

I opened this link: https://sb360.online/aogbf1?
(This is virtual walk). He's loading, but image not displayed.

Actual results:

Webrendering for Intel and AMD was introduced in version 79. This is the problem. In v78, this problem is not present.

Expected results:

When I go to the config: about and find the gfx.webrender.all option and set the value to true, the virtual tour displays correctly. The photos show up.

This problem occurs on 1 of my 7 computers.

Hi arks,

I could not reproduce this locally.
Could you:

• Attach the information in "about:support" (navigate in url bar)
• check if this is present in the latest Firefox nightly release (https://www.mozilla.org/en-CA/firefox/channel/desktop/)

Thanks!

Comment 0 is a bit confusing: Does it display correctly after enabling gfx.webrender.all and restarting Firefox or does it cause the problem?
I assume this bug is a duplicate of bug 1656956. (If not, the regression range is likely the same.)
