I tried asking in Discord a few days ago.

I also tried removing everything, including sodium & co, but without any difference.

I'd like to know if this is a known problem and if the cause is avoidable... Before turning it off in the modpack and forget about it.

what fabrication version / minecraft version?
might be a mod conflict, did you try with just fabrication installed?

Yeah, pretty much a clean modpack. Using fabrication-3.1.9+1.19

EDIT: I meant 3.2.6, but it was the same with 3.1.9

But I've noticed the problem in earlier versions.

i'm not getting it and i have no clue what's going on, maybe una does?

It seems like the particle is getting a texture somehow?

Could you send us a crash report and game log? Hold F3+C for 10 seconds to crash the game even though it's working normally — crash reports contain a lot of useful debug info.

crash-2023-05-02_03.21.12-client.txt
latest.log

Normal GPU (not some jank Intel thing, or some antique card), Windows, no OptiFine or even Sodium, nothing exceptional in the log. Hmm.

So they are actually flickering, that's strange...

the zip has two versions of fabrication please try each one. this is probably just my blunder mixing up max/min UV
(as to why it only happens you, i have no clue)
test.zip

Both seem to work. The wool one has a gray wool texture (working normally).
