Bug Report ID: #3,815,772,902 Pausing in Act 2 Pyramid with Darkness Effect Fills Screen

If you pause in Act 2 in the pyramid with the darkness visual effect active and then alt-tab and have the game window hidden by another window then the dark streaks that periodically fly across the screen streaks won't fade out at the end of the trail like usual. This causes the dark streaks to fill the screen eventually. Unpausing causes the streaks to continue their motion and clear up, gameplay is able to resume normally. See the images for an example.

While paused:


After unpausing as the accumulated streaks clear out:

I was alt-tabbed into a browser, specifically DuckDuckGo's browser which uses Microsoft's WebView2 so the Blink engine. I did not test with another window that wasn't a web browser or a browser with a different engine like Gecko (FireFox).

The alt-tabbing with a streak already on the screen caused it to immediately become "stuck" but to fill the screen to the level in my images it took about 15 minutes.

Does this same effect if you pause when you start a vaal temple map and run to the door and when it opens the door spews out a bunch of stuff and if you pause it there wait like 5 minutes you get your screen filled with stuff
