Hello, apologies for the delay. I’m not seeing any other known issues or fixes that might address this. Without a repro case or steps, we’ll need to collect more information, logs, and try to catch it when attached to a debugger to find out what’s going on.
Slightly moving a node in the base material and hiting the apply button “fixes the issue”
Does the issue happen in the base material or only material instances as mentioned in the referenced thread?
