Render target memory 2D high performance cost as time increases

I have recorded two Memreport with a 10 minute idle interval. I have discovered that Render target memory 2D usage increased by alot even though i did not add any new actor to the scene.

From:
352892528 - Render target memory 2D - STAT_RenderTargetMemory2D - STATGROUP_RHI - STATCAT_Advanced

To:
1078415524 - Render target memory 2D - STAT_RenderTargetMemory2D - STATGROUP_RHI - STATCAT_Advanced

Once i restart the editor, the memory usage does reset to the number close to 352892528, therefore i suspect there is a memory leak somewhere slowly building up just by leaving the editor idling.

So what could be the cause of this issue and are there any effective steps so that i can perhaps track which object that is causing my Render target memory 2D to build up?

The issue is described here.

Thanks for replying. I followed the thread and ensure that r.gpucrashdebugging is false. However, the Render target memory 2D continue to build up. I suspect it may be some other factor causing this.

Any other clue for this issue?

Console command alone is not enough to disable aftermath in earlier versions.
