TBC Classic: Issues with Consecration spell effect (visual only)

I have noticed something weird (and I’m not crazy). The spell effect of Consecration is much “dimmer” since a few days ago.

Example before: https://clips.twitch.tv/BlindingPluckyLocustCharlietheUnicorn-8h5aia1ssYvHWg8Y
Example after: https://www.twitch.tv/jokaah/clip/ArborealFlirtyHippoDoubleRainbow-4_sYOF4D9_A83bZ2

And no, it is not only because I am in a darker environment in the first clip - I have checked.

I am not crazy, right?
This is actually bothering me a lot. :upside_down_face:

Should probably add that I’ve tried disabling all addons. Turned graphics down to lowest, back to highest and pretty much everything in between. Even updated my graphic drivers and Windows.
