In Roblox Studio, beams are not shown. They are invisible or missing. Neither image beams nor normal color beams show up.
This was first observed by at least 3 individuals (including myself) today.
Expected behavior
Beams should display normally.

I was one of the people to observe this, it completely makes any beam disappear:

Also having this issue. Any fixes for it so far? Seems to be when testing in studio and in non test mode they disappear, but when testing from the roblox game client they work perfectly fine.
I am also having this same bug. Beams are just invisible.
i had a nextbot game i was working on and OMG. i thought my game was messed up and it was… real annoying to say the least
it was like 6, 5, or 4 CST time when i found out
Dude, me too! My bullet tracers, which are made with a mix of beams and trails, just don’t appear! I was thinking they weren’t loading, but alas! I pulled it out of replicated storage; ITS INVISIBLE!
ME TOO! All the beams I used for my lights suddenly disappeared for no reason… Bump this so a fix is found
I am also having the same issue. But in Roblox Player app no.
Confirming that beams are not visible in Roblox studio. In any game / any place I open.
Can confirm, i thought my flashlight tool broke today. There is supposed to be a beam here:
Same for me, my bullet trails and even bullet holes (which also use beams) aren’t showing up
I can also say that I’m experiencing this issue. Thanks for creating this report.
I thought I was doing something wrong with my beams and was going crazy! 
On the bright side at least Roblox might be updating trails and beams.
Or they might have just broken something when working on something completely different.
I have the same problem. I think it’s a Roblox Studio bug.
Beams don’t show up in all of my games as well, I think it’s a Roblox bug indeed.
Having this issue too, seems like it was caused by some sort of update as everyone suddenly has it on the same day O_O
Had me tripping for 20 minutes trying to debug my code 
I agree Beams can’t be seen anymore, you can try yourself with any waterfall model from the Toolbox:
Can confirm this also happens to me. No laser pointers for me ;-;
I noticed this as well and thought I was going crazy. I hope this gets fixed soon.
