Bug VFX Graphs keep recompiling

    My VFX graphs get recompiled any time I modify the Unity project. Anytime I hit "Save", I get to spend the next 7 minutes waiting...

    This is a new behavior, appearing in 2022.2.2f1. Definitely not acceptable.

    Is my configuration wrong, or is this a bug?


    Update #1: I clicked on a Material (w/custom shader) in the Project view. Boom. All shaders & graphs recompile.

    Update #2: I added a component to a GameObject. The component has no VFX dependencies. Boom.

    Update #3: Still exists in 2022.2.3f1


    Last Edit: I realize that this is a crap bug report. The steps to reproduce are so random that it's just... ...well, I guess I just didn't want you all to think you'd "fixed" the recompile issues.

    Hey, that sounds really frustrating :( Regarding the updates section you wrote, it's really odd that something that doesn't have VFX dependencies can cause VFX recompilation. I've been working on a fairly large test project recently, but haven't observed anything similar (it would lead to around 1 hour of recompilation, in this specific case, ouch!). That being said, do you mind reporting a bug and sharing its number here? I'll keep an eye out, and if it's valid, I'll forward it to our engineers to investigate further.
