Light from spell effects sometimes linger too long?

[Mookeylama]

occasionally i'll cast a spell and the area where the spell landed will be lit up a bit. obviously mage light, but also flame, frost n lightning spells too. that's all fine, but the light effecting the area will remain way past the spell.

any ideas on this? vanilla bug?

thanks

Pretty sure vanilla bug. As long as it's not too much of an eye-sore, I wouldn't worry overmuch about it. I still see it on occasion.
