Lag after CC effects in Visions

I’ve done a couple Horrific Visions today, and in both of them the game felt reasonably responsive most of the time. However, every single time I got polymorphed, stunned, feared, etc. the effect’s timer would hit zero and nothing would happen for a few seconds. Then all of a sudden I’m free to control my character again, but I’m taking a whole bunch of damage and sanity loss from whatever happened while the game was lagged out.

Has anyone else had this issue lately?
