flicker strike bugged?

I encountered a possible bug with flicker strike, sometimes during gameplay flicker strike will stop dealing damage. I am still hitting and jumping from enemy to enemy but I don't deal any damage. the first time I noticed this was during the trial master boss fight. but since then I've also encountered it in the citadel fight against the count and during a trial against normal enemies. I've got recorded gameplay of some of the events if that would be helpful

Yes, it happens a lot, and many others are reporting it. I haven't figured out how to avoid it.
