[UE 5.4.4] Huge lag spike when compiling blueprint with class defaults open

Hello,

There seems to be weird issue where if you have class defaults opened and compile BP, you get large freeze/fps drop.

Steps to reproduce

  1. Create BP with Character Parent Class (no need to change/add anything)

  2. Class defaults details tab opened

  3. Compile
    compile

  4. There is noticable stutter

  5. Close details tab or switch from class defaults to class settings and there is no stutter/lag in this case

Two people on my team are experiencing this, so I assume its not just system/drivers issue. Any fix or help would be appreciated

  • Thanks!
