Trial 4th boss Hourglass phase bug : time ticks WAY faster than it should

During Zaroth's boss fight, something is causing the time-gated hourglass phase to be WAY shorter than it should be.

Here I have a regular clip of a friend failing the phase, representing a normal duration (13 seconds from the moment the clock starts ticking): https://imgur.com/a/1oLjLVt


Here I have another clip of me failing the mechanic (with 90% ms), but the duration is much shorter (5 seconds) :

As for afflictions, I had faster traps, but I also had the slower traps boon, and I've had this happen in a much worse degree (about 2 second duration) in another run with only slower traps boon and no faster trap affliction (I have no idea if those afflictions interact with it, but just in case).


I suspect the bug might be caused by chill/freeze, or maybe some boons/afflictions, as it only started happening after I swapped to frost mages from arsonist. It could also come from the previous patch.
