Changed status from 'Needs Triage' to: 'Confirmed'
Can confirm the slowdown, will check what is going on

If some user action changes relations, it is to tag relations for update.
Just noticed there is a duplicate report for this, see #83271 (Displace modifier with Image Texture causes scene slowdown), no need to have two reports open for this, will merge them.
Closed as duplicate of #83271

Coretag, will leave classifying to the module members
