Description

Memory leak when comparing scale value with 0 on transform. It appears that the memory used by the editor increases by 25-50 mbs while comparing the scale to 0.

Regression (no) issue (does) occur in 4.11.2.

Steps to Reproduce
  1. Download, unzip, open attached project
  2. Open Maps>ArrayVisualizer
  3. Press PIE
  4. RMB Windows Toolbar>Open Task Manager
  5. Switch to Processes and find UE4Editor.exe (note memory used)
  6. In PIE window, press Spacebar to compare transform scale to 0

Results

Memory begins increasing by 25-50 mbs. This does not revert to a lower memory use value when PIE is exited or spacebar is pressed again to stop comparing the value to 0.

Expected

No memory leak occurs, array visualizer compares scale of transform by 0, Green waves on screen slow down.
