Some of my skills are going in slow motion (literally)

Lately I've noticed that some of my Warrior skills (which never behaved this way before) are suddenly playing out in slow motion, like I'm stuck in a temporal bubble. It's not happening to all skills, though.

For example, Rolling Slam, Hammer of the Gods, and Perfect Strike are affected.

I recently picked up Giant's Blood to dual wield two 2H weapons, could that be causing it? I have around 500 Strength, and both weapons require about 330, so I’m not short on stats.

Oddly, Leap Slam still feels totally normal, but Rolling Slam and a few others feel extremely sluggish.

Anyone else run into this? Is it a bug, or am I missing something?

Thanks!

Here is a video of what I'm referring to: https://youtu.be/C6IB7ABO9RE?si=32H6qAYfsB3M5SSY

I've noticed a few instances of it happening with my mercenary too, using crossbows.

I assume it's performance/network related, at least in my case. It doesn't happen that often, but when it does, it lasts for a handful of minutes.

After you ported back to town and came back, did it fix?
I've noticed a similar bug too, where some skill speed debuff would invisibly apply...
