Im experience memory leak while blueprint editor function library window opened after moved to 4.9.2

What should i do?

After Closing all opened function windows, compile and save library - leak is gone. But is still have “corrupted” copy of the project laying around, with compiled and fully functional library which has memory leak after opening function library blueprint.

Hey CriErr,

If you have a corrupt version of the project, would you mind uploading it to a cloud storage service and then PMing me the link on the forums?

so, how is progress?

because i found it can happen in Blueprint interface as well

repro for 4.9.2:

  1. Create new project, i create third person one
  2. Create blueprint interface
  3. Start creating functions, just by clicking + function on tab
  4. After 10-15 of them, i would guess it depends how many need to fill your current opened functions bar
  5. Start double click on their names to open currently opened tabs - the more you click, more memory would leak.
  6. Moving frame position (hold rightclick and drag in blueprint editor window) increase rate of memory leak.

Hey CriErr,

I’m not sure why I didn’t realize this sooner, but we already have this entered as a bug (UE-21203). It has to do with how the UE4’s Slate UI handles the text in a tab when the tab shrinks for whatever reason (a ton of other tabs, making the window smaller, etc).

Thanks for reporting this though. It is still under investigation though and there won’t be a fix for 4.10.
