minor harmless bug. Dynamo ult on me as soon i ulted, it has a 2sec period it seems.
Get fixed on respawn or probably ziplines. Happened to me once, dont fully remember what fixed it.
This bug is occurring the majority of the times I use Haze ult, not just when cancelling it immediately. It's not minor or harmless, because it causes your crosshair to be offset/desynced from where you're actually aiming, so aiming accurately becomes very difficult. I haven't found a way to fix it other than ulting again or dying.
Edit: I haven't been able to reproduce it in sandbox, but it's happening to me multiple times per game. 28835341 is a match ID where it happened multiple times (Haze ult causing the game to freeze up also happened on my first ult that game ). Another report said it happens when you get stunned during ult, but that doesn't seem to be causing it in sandbox.
I checked my replay of that match, and it appears the replay doesn't show the bugged FOV, but you can still see the offset bugged aiming after my ult gets interrupted at 32:08. My bullets are fired significantly to the left of my crosshair until the next ult or death.
