My video goes wonky near the end of a hard section - such as a zone 4 or 5 section. I’m not talking bursts of sprinting but a longish section, I’d guess at least 5 or 10 minutes. The video looses saturation and horizontal lines appear. This only happens during workout, not during free rides. It’s almost like it’s warning me I’m working too hard. I am working hard usually (but not always my hardest) and am pushing my hr but not up to what I *think* is my max. This clears up when I finish a section right as I hit the see-through colored semi-circle on the road.
Is this some feature I can’t find? I’m using a new macbook pro with their best graphics card. Sometimes I have it hooked up to the tv mirroring the signal but not always.
