Non-stop scene update

Wondering if someone bumped into this problem. Solaris keeps updating scene non-stop which makes things barely working. During this the pencil icon keep flashing and the CPU is at high load.

The problem seems to be coming from the materials. If I disable some of them (narrowed it down to 3 of them but still not sure, there's 100+ of them) it stops, if I disable their first textures it stops. I tried everything like rebuilding the materials from scratch, renaming whatever I can and replacing the files, but it returns again and again.

This behavior inconsistent, sometimes I manage to stop it, and it's back after Houdini restart. Sometimes I see a warning that the material have time dependency, but it does not. This never happened in 20.5, now I am simply stuck and unable to find the source of it to properly bug report.

H 21.0.559-566 on Win 11

UPD. There's another suspect - karmafogbox LOP, i think it hasn't been updated for H21

I've had that issue before when I had more than one viewport open at once.

Hey, thanks for the hint!
I definitely have just one viewer open.
Actually I more confident now that the culprit is the fogbox LOP, seems like its setup interferes with the other material parameters (including the material time dependency which is on for it). I recreated a simpler setup of it, will see from here.

I have encountered this issue. The scene did contain a fogbox. I also use two viewports most of the time while working in Solaris.

If I remember correctly this error https://www.sidefx.com/forum/topic/102050/ [www.sidefx.com] did also constantly print. Making the light linker node crash Houdini, when I tried to use it.

Well, it's even more weirder.
I added a curve box as a guide object (same way as the fogbox uses) and the problem returned even with my simplified setup. As soon as I delete these curves the problem goes away.
I have no idea what this is, but if the devs come by here, please pay attention to this weirdness.

Is that a reproducible error setup? If so, I'd suggest filing an RFE.
