Around 3:50 PM CT today (Wednesday, June 17), I opened my place in Studio and noticed these unusual glowing colored patterns radiating from certain parts of my building. This was NOT happening last night:

After a little experimentation, I’ve figured out the basics for a repro:
Lighting.Technologyis set to Shadowmap. This bug does not affect Voxel or Compatibility
Lighting.EnvironmentSpecularScaleis set to any value above 0 (Higher value intensifies the glow)
Place has visible BaseParts
Here’s what it looks like in an empty place file:
Most BasePart materials are noticeably affected by this. Effects carry over to Play Solo in Studio. It seems to vary depending on the lighting settings. Does not appear to impact Terrain.
I suspect this has something to do with the latest Roblox release, 437. Assuming that the repro requirements above have been fulfilled, this bug occurs in all games.
