Hi Lukas can you provide me a YouTube link for me to text to reproduce this bug and also can you provide me your about:support information to help me find the bug.

Hey Amdrew:
This is one of the distorted videos:
But it seems that all 360 videos (you can choose your own perspective while watching) have the same colour problem.
On other browsers as safari the videos still work fine.
I don't actually don't know what this means: about:support information.

Hi Lukas,

I was able to reproduce the issue reported on iMac OSX 10.15.3 using Firefox Release version 83.0 and on Firefox Beta 84.0b7. However, I haven't been able to reproduce it on Firefox Nightly 85.0a1 (2020-12-02).

I wasn't able to reproduce this on a Windows 10 machine.

Can you please download Firefox Nightly and test if you can see the correct colors as well? You can download it from here:

Since the issue seems to have been solved on the latest version of Firefox Nightly, it means that it will be fixed when Release version reaches 85. But just in case please let us know the results you get so we can continue investigating.

Thanks in advance,

Hi Virigina,

I tried Firefox Nightly and yes, it worked out fine. No displaying problems anymore.
I hope the new version comes soon, because this bug looks quite bad and I'm just launching a new 360 performance project.
Anyhow, the bug seems to appear only with the AMD Radeon Pro 5500M and/or the i9. I asked a friend with the same mac but cheaper graphic card and i7 to reproduce the bug - he couldn't, displaying worked out perfectly fine.

Thank you so much,

Youtube uses WebGL to draw 360 video contents. Moving component to Graphics.

Hey guys,
still waiting for a new firefox version where this bug doesn't exist anymore.
Yes, with the firefox nightly it works out fine. But nobody uses this version.. I hope that not to many people are using firefox with a mac book pro 16, i9, AMD Radeon Pro 5500M and trying to watch 360-Content on youtube. Because it looks quite poor..

Anyways, thanks for your responses and ideas.
Best wishes from Vienna,
