The issue

We use a video recorder script that creates videos using this package, the videos are tours of a room and an audio clip is played through unity over the top. This functions perfectly fine on our Mac platform. On Windows however, it only works well the first time, if a second video is recorded we incur a memory leak of a few hundred mb every second, until we reach max memory and the application crashes. This occurs in builds, but also in editor. On occasion the leak does stop however the accrued memory is not released at any point. Additionally we have had builds were this issue was not present. After memory profiling we can see the memory is classed as untracked memory, meaning it must not be managed by the Unity Memory Management API (attached). It appears in private and system heap. We initially used an older version of the package but after trying the newest one 5.2.4, the issue persisted.

I should mention, we destroy the CaptureFromTexture object between each recording. And add the component again when it is time to record another.
