Hi, I think you are talking about the effect of glare on the glass of the screen?
If so you just need to adjust the Tube Static Reflection Opacity in the [ TUBE STATIC REFLECTION IMAGE ]: section, you can turn it up to have as much tube reflection as you like.
What was there previously was what I personally liked, but many users wanted to remove the tube reflection, so I decided to set the default to 0.
Here are some examples:
No Tube Reflection
A bit (Similar to what was there before)
and Waaaayyy too much
