I was in Grizzly Hills, doing the solvent repeatable, and I look as if i was swimming when i stopped moving, or casted. i figured out how i got it, and decided to post here
Step 1: take your mage to grizzly hills, and fly down to the docks.

Step 2: Take the solvent out of the boat.

Step 3: exit boat, pop Slow Fall, get on your flying mount, go up in the air about 20 feet
Step 4: move forwards and dismount, it should look like you are swimming to the ground

Step 5: when you are close to the ground, Blink. you must do it before you hit the ground.
after that, you should have the same graphic glitch i received.
you can turn in the quest and still have the glitch.
here are some screenies of the result.
