garduz but when it does "the bug" it's not hotter then when it doesn't
I don't think you could possibly sense the difference with your hands on the outside of the headset's casing. Imagine if a CPU or GPU would have time to heat up its surroundings significantly before being throttled, it would probably be too late for damage control.
Anyway, this was just a guess. Something is causing those refresh rate fluctuations but at this point there is no way of telling whether it's the app or the OS or the headset's firmware.
Edit: Did some testing for 10-15 min on Q3 with the right panel in view. For a while, I turned everything on I could think of to make the fps counter drop from 120 to around 35. But during the whole time, the refresh rate setting remained on 120 Hz.
