Flashing red circles.

I was rushing a Primordial Blocks map with a Delirium mirror encounter, then get to the Ultimatum of the area, started it and when the counter was in the middle, a lot of red circles started to flash (its pretty bright).

My build is Blazing Salvo Mines Saboteur and the only unique item I have is Tremor Rod (I write this 'cause I forgot to show it in the videos).

That was the first time, then in the next map and the next two maps (only when I started the Ultimatums). If I get far enough of the Ultimatum they disappear (or if I abandon the instance).

Here are 2 videos of it.

It's not a gamebreaking bug but is annoying af. I'm not playing atm, so I can't be sure if they are still there, but if they are, i'll update this.

I'm also having this issue.
However, for me it's always, even in character selection.

I'm on a new system. Worked on my old without a problem.

GPU is RTX 2060. drivers are up to date.

Help appreciated!
