Rev - Glint facets pulse through once
to solve this put water skill on your revenant. going in water with no water skill cause this bug. on the glint skill. it also happen in the dry top map in the sand storm. some time in pvp and a couple of other area. like I said the fix is to equip water skill on your revenant. only 2 legendary hero have water skill. so look this up.
I have reported this bug to anet when hot came out. seams they never fixed it.
