Glow Effect Glitched in Heavy Lighting zones

[SilverSun247]

Date & Time: 7/3/18; since 4.35 onward
Frequency: Consistant
World name: Malboro
In-game time: Cruadin (Dark Knight weapon from Castrum Abania, Lv. 69)
Tested on 5 clients, all were PC, all had this effect. Various specs so it doesn't seem to be a shortcoming of a computer itself
Edit: Tested on a first gen PS4, lines up with issues on PC

Normally the sword does not glow except a small green shard. Since the patch hit, the sword Cruadin glows in its entirety when used in areas with a lot of lighting (the sword glows normally in try on, and in a personal house with few lights ). In more open world areas, such as the Goblet, it would sometimes blink in and out of working correctly, but I couldn't replicate this (something to do with models, PCs, or lighting, maybe?).
