Fighting Butcher Invisible Fire

When fighting The Butcher, I am greeted with the furnace squares not showing which tile the fire will blaze, resulting in my imminent and speedy demise

my fire beam is not showing

Same here. Had to search the internet to look for the Butcher mechanics to understand what killed me so quickly during those interludes when he is invulnerable, only to learn he rotates some fire beams that never appeared on my screen.

I tried other graphics settings but nothing makes those beams appear. So, for short, I just cannot fight the Butcher.

The two posters above wrote 10 and 9 days ago. No response from Blizzard.

Do the devs care at all???…

I had this problem too and found a video that solved it; My graphic settings were set to low, when I change it medium the fire lasers became visible. It worked for me, hope it works for you good luck.
