New Update Today Broke PointLights

Reproduction Steps
I’m not 100% sure the cause of this one, I do know for sure it’s a result of the new Roblox update today, and not an issue of mine. I can reproduce it in my games by enabling a pointlight, then disabling it.

Expected Behavior
I expect after disabling a PointLight the light effect is no longer visible.

Actual Behavior
PointLights remain after being disabled, they even remain after EVERYTHING in the workspace is deleted.

The PointLight in question was clientsided, and the bug seems to replicate to the server as well:

UPDATE:
Roblox Studio updated again, the issue has now gotten significantly worse… This one isn’t even a PointLight, I think it’s a reflection of some kind but I have no idea what’s causing it.

This is in edit mode BTW, so nothing is running.

Same here, after I disable it they’re still visible and are flickering.

I’ve received a lot of reports of same issue happening in my game and found steps to reproduce it:

  • Enable future lighting
  • Insert Part
  • Insert any light instance (PointLight, SurfaceLight, SpotLight)
  • Disable/delete light instance and notice how light did not get disabled

System specs:
CPU - Intel Core i5-4690 @ 3.50GHz
GPU - NVIDIA GeForce GTX 1060 6GB
16 GB of RAM

I also want to mention that these bugged lights sometimes rapidly flash and the bug happens 100% of the time thus absolutely ruining lighting in games like mine where it dynamically moves around the map and can be disabled

Yeah future lighting is not working


There’s no invisible parts the light just teleported there.

Having the same issue. This issue is also affecting other lights, such as SpotLights. After disabling, the lights remain, sometimes flickering, or constantly jerking up and down. Some chunks of the screen render the light properly (by not drawing it). I’ve attached a video to visualize it more easily. I have all beta feautures enabled.

After talking with others, it looks like it happens to everybody. Simply enable Future lighting to reproduce, it happens both in studio, and live games.

My studio had similar problem yesterday, as soon as I enabled Future Lighting my studio window lagged like crazy and I could barely move my mouse at like 5fps and the 3D viewport was going crazy too with some 2D black squares glitching out for every render update.

Here is what I found so far:

Issue 1
  1. Set rendering option to Vulkan.
  2. Restart Roblox Studio.
  3. Enable Future lighting.
  4. Move your camera around.

Issue 2
  1. Set rendering option to Automatic.
  2. Restart Roblox Studio.
  3. Insert any light instance (eg. SurfaceLight) to a part.
  4. Either set Enabled state of the light instance to false or :Destroy() it.
  5. Move your camera around the position where light was/is located.

I’m using windows 10, graphics mode in studio settings is set to automatic, so probably it is directx

Not sure if you’ve shipped it yet, but as of today the issue seems to have gotten worse. LightSources in game still stick around, but before they would disappear when another lightsource nearby was updated. Now this doesn’t seem to happen and instead they flicker horribly.

I am running Windows 10 Pro

It’s important to note I am not using Roblox from the Windows Store… I’m using the version direct from the website.

Can confirm this is still happening in my case almost exactly as you described.

Windows 10 Pro
Intel Core i5-7600k
Nvidia Geforce RTX 2060 Super, DX11

Also not on the Windows Store version, it’s the standalone version.

This isn’t fixed yet, tested right now and still happening, pretty frustrating.

It’s not shipped yet. Note “will ship ASAP” in their post. Roblox generally ships engine updates in the middle of the week.
