Weird memory consumption

Hi friends,

I’m running a very simple Windows/OpenGL application, that creates 20 RenderWindow, with default properties / no Actor, and call Render() on each one.

When creating RenderWindows, total application memory stays < 300MB.
As soon as I call RenderWindow.Render(), memory goes up by +100-200MB for each RenderWindow.
For 20 RenderWindow, total memory goes above 2GB.

My questions :

  • What is the cause of this +200MB memory consumption for a simple empty RenderWindow ?
  • Would it be possible to minimize/avoid it ?

Tks :slight_smile:
