UE 5.1 still has this issue. I set the Invalidation Box as the root, and found that playing UMG animations or changing brush for an image will trigger the invalidation, but not always trigger for set text of text block that not update frequently. Setting Invalidation Box/text block volatile still doesn’t update. So far I made a one frame UMG animation in order to trigger the “set text”, can do the job, but cumbersome and unwise.
