UE 5.5 has broken Blueprint Action list loading, causing severe lag

Hi,

for a while, I was wondering why is Blueprint scripting in 5.5 so much more difficult. I found that I very often start typing after opening node graph action list just to find that a couple of the first characters of the word I’ve typed are missing. It made the BP scripting experience miserable.

I finally found out why!:

UE always had async loading of the action list entries where it would display the list immediately, and then lazily load the contents while displaying small blue progress bar at the bottom. However in 5.5 (or possibly 5.4, I have never used that one), someone has broken it, so now the action list will not pop up until all the entries are fully loaded.

If you open the list and start typing, it will often discard couple of the characters you type, and overall using BP editor now feels very laggy.

So if you are using UE 5.5 and have discomfort doing basic BP stuff, even in completely blank project, now you know why :smiling_face_with_tear:
