Flickering rendering target on the UI

Hello,

I have created a scene component which writes to a render target. I have then created a material with that render target so I can put it on my UI as a kind of minimap. However, on my home computer, the UI image flickers weirdly whereas on a different machine it works fine. I was just wondering if anyone knows what the cause of the issue could be?

Hey, sorry to necro this, but did you every find out what caused this? I have the same situation, and the same issue (UE 4.27.2)
