Child panels cooking when controlling display par trough expression

Hello!

I was optimizing my UI, trying to reduce panel cooking and noticed this:

When manually toggling the display par of a panel COMP, only that one cooks. However when that same display par is controlled with an expression, it being toggled also cooks all it’s children.

Toggling that display par via a python script gives the first behaviour, so that’s the workaround for now, but I’m not sure if a par expression cooking all the children panels is the desired behaviour.

I’m on an M1 pro, Macos Tahoe 26.3, touch version 2025.32280 but @timgerritsen could also reproduce it (and found the workaround).

Curious about it!

Like coelepinda said, it also happens on my machine (windows). I’ve made a quick example to demonstrate this cooking issue.

Cheers,
