Poor memory management when changing scenes causing permanent memory increase #5921

Open ZachjuKamashi opened 10 months ago

Is there an existing issue for this?

Describe the bug

There is a permanent memory increase after changing scenes with regarding events which can result in very high RAM usage in certain cases, enough for the project to run out of memory and even crash devices.

Here is a video showcasing how the memory usage performs with this test project.

This is probably because the generated code is clearing object lists before the events instead of after them so some instances stays in memory until the scene is run again.

@D8H It's been half a year, are there any updates on solving this issue?
