Broken screenshot; Decreasing lightness

My box:
Beelink GT1 Ultimate, CoreELEC (official) 8.95.5

Two issues are found:

  1. Screenshot is broken. Please refer to the pic
  2. After the box is running for some days, the brightness will decrease.

Are they fixed ? or New issues?

Anyone help me ?

I was with the brightness issue too with 8.95.5. I’m gonna test 8.95.6 to see if the problem is solved.
