PixelStreaming Memory Leak at UE5.1

[Sisangboro]

I’m trying to use Pixel Streaming in Unreal Engine 5.1.
Activate the Pixel Streaming plugin, after packaging the project, and create a shortcut to the game.
And I run the game.lnk with matchmaker server and signaling server.
While the game is running in renderoffscreen, it takes up more and more memory, and the game ends due to lack of memory.
This process seems to last approximately 10 hours(Approximately 1~3 megabytes per second).

I am using i5-13400F, 3060Ti, and 32GB of memory.

The solution in Unreal 5.2 GitHub pr#10637https://github.com/EpicGames/UnrealEngine/commit/eb1286a661f85c3b2380346466b6549e424d3017 does not seem to be applicable to 5.1. (AVCodecs does not exist in the plugin)
I tring upgrade the project to 5.2 and attempting to apply the method in pr#10637.

Is there any way to solve this in 5.1?

I found out that the cause of the project’s memory leak was Planar Reflection, not PixelStreaming.
When I deleted one planar reflection actor placed in the level, the memory increase of 2 to 3 megabytes per second disappeared.
