Weird issue with colour changing

Hello.

I've been having this weird issue lately, which I'm not sure how to describe. I first saw it on Wednesday (under v1.32.0.12) and again yesterday (under v1.32.0.13), so, if it's a bug, it was introduced in .12. I say "if it's a bug" because I only see it in one specific sim and nowhere else and again not all the time (yesterday it happened three times, on Wednesday it happened once, on Friday when I was there again it didn't happen at all). What happens is this: the sim looks normal, but at some point some colours get… weird. I shot pictures, because I can't describe it. The sim normally looks like this:

The first time it happened, it became like this:

The second time it became like this:

The third time it became like this:

It's like someone changes the environment on purpose, but they don't. It can be fixed by toggling PBR off and on again (or relogging).

Now, the sim is kept locked unless there is an event, so I can't lead you to it, unless I add you to the group first (if you want me to, I will). I'm attaching the log from yesterday.

My system information is:

Mesa got updated on my system the other day, so that might be a reason. I also theorise (but don't know for sure), that at least the first time this happened yesterday, the sunset passed and changed to night.

I don't know what other info to give you.

Thanks.

Likely a Mesa bug: simply revert to former version...

Note: the only change in rendering that went in v1.32.0.12 was about the PBR mode, and can be disabled by setting "RenderSkyReflectionDesaturation" to 1.0 or less (e.g. 0.0). There has been no noticeable change (at least none that could, even remotely, explain this) in rendering with v1.32.0.13.
