Random graphic glitch - POE 2

Hi there!

I have a bug on my instance occurring randomly where the screen become black and a few graphic glitches flash on the screen.
I attached a couple of images to give you an idea.

Don't know if it's related, but I can see that the "shade" bar on the graphic chart is always fully green, as you can see in the following image.

My specs are:
- NVIDIA GeForce GTX 1060 6GB
- AMD Ryzen 5 2600
- 16GB DDR4 RAM

Cheers
