Lighting & Anti-Aliasing issues. Ghosting/Flickering.

Hello everyone.

I have a very weird issue that I have recorded in the attached video (Converted video into below gif as video was too big)

For context:
This is a “Blueprint_Terminal” system that I have where the player can interact and type some commands (think Linux terminal). The “text” itself is a Widget Blueprint. The terminal itself is one static mesh made of 2 materials. 1 is the screen itself (which is an opaque transparent/translucent object) and 1 is everything else. I am highlighting the screen as I believe that this might be important?
Global Illumination is set to "Screen Space (Beta) and AA is set to TSR.

My issue in here are actually 2 issues:

  1. The “Flashing” of lights that is visible when the player interacts with the Terminal. This appears to happen regardless of whatever Anti-Aliasing I have (Tried all, including None). I am guessing that this might be happening due to the Static Mesh of the blueprint.
  2. The way that the text slowly “fades out”. I found that this is caused by Anti-Aliasing. If I change it, it too stops doing that, but of course that the quality of it drops hard. My question would be, could I keep the current AA but maybe increase the “speed” at which it updates so that it makes it seem more seamless? If this is a possibility, would it be feasible? I’m talking about performance here, because of course I can’t just crank it up and expect nothing bad to happen.

And I realized that the second part of the gif wasn’t fully uploaded.

Here’s the “ghosting” section in action.
