Dice rolls in DNDBeyond randomly skyrocket my gpu usage and causes my screen to go black and crashes my GPU.
Am using Linux, with an RX6600 and using Vivaldi.

Seems like a problem with your device.

I've tested the dice roller on:

Windows 10 Laptop - six year old, refurbished, low specs - using Firefox, Chrome, Chromium, Opera, Opera GX and Edge. 
Windows 10 PC - 4 year old, new, mid-specs - using Firefox, Chrome, Chromium, Opera, Opera GX and Edge.
Windows 11 Laptop - 1 year old - mid specs - using Firefox, Chrome, Chromium, Opera, Opera GX and Edge.
Android Smartphone - 6 year old, mid specs (for then) - using Firefox, Opera GX and Chrome.
Various iphones and ipads but can't remember how old they were or their specs, was years ago now though - Firefox, Safari.
Xbox One S - Edge.

No GPU issues at all for any of it.
