Yes, they were happening ever since i got the machine in Batch 9 (Loaded 3.03 and Fedora 40 beta on it day 1)

They tend to show as the massive performance swings and frametimes being out of whack every time it tries to use the charger - which makes me almost nauseous - however 3.04 seems to limit far more, and i am now stuck at the lower performance level entirely as long as one of the affected chargers is connected.
Worse than on battery only, even.
