DebugDrawHelper memory leak in editor

DebugDrawHelper memory leak in editor

Steps to Reproduce
  • In QAPawn.h, in AQAPawn, add:
    virtual void Tick(float DeltaSeconds) override;
  • In QAPawn.cpp:
    • add #include "DrawDebugHelpers.h" at the top under #include "QAPawn.h"
    • Add:
void AQAPawn::Tick(float DeltaSeconds)void AQAPawn::Tick(float DeltaSeconds)
{ 
    ACharacter::Tick(DeltaSeconds);
#if ENABLE_DRAW_DEBUG 
    DrawDebugSolidPlane(GetWorld(), FPlane(GetActorLocation(), FVector::UpVector), GetActorLocation() + FVector(0, 0, 100), FVector2D(100, 100), FColor::Cyan, false, 0.0f, 0);
#endif
}
  • Launch QAGame
  • Turn on the Memory counter (Edit->Editor Preferences) Performance -> "Show Framerate & Memory"
  • Pressed "Play" (PIE)
  • A debug square draws around the character's waste.
  • Move around for a few seconds to stabilize memory, wait a minute.
  • Stand still, this can take a few seconds, but eventually the memory counter will steadily increase several MBs per minute.
