Is this still reproducible for you?

Hi Ryan,

Huh, so I can reproduce this.
The console is full of this spam, however:

However with that pref disabled, everything seems to render fine!

This is probably us messing up a texture format. I'll run it in a debug build, which should show if that's the case.

Jeff, were you able to investigate more on this bug? Thanks

Comment 8

[Pascal Chevrel:pascalc]

Jeff, any news? I would take a low-risk patch for beta as it affects a major site.

Emil, could you confirm that you are still experiencing the bug in 63/64 on macOS? Thanks
