The behavior has only occurred when road and traffic conditions have forced me to have a feather-light touch on the accelerator at very low speeds (under 10MPH).
I think the seals leak on the clutch and initially only effect the 1st to 2nd gears because that's when you notice it first (lots of torque = more slipping)? It eventually starts slipping in gears 4 and 6 (at least in my car) which just ruins the driving experience, imho.

What I'm assuming it does effect is the adaptive programming and probably whatever "micro-slipping" is (lol, more like macro-slipping). My car is over-reving into second and engages super-slowly. People are honking at me at lights because I'm accelerating too slowly - not to mention the car dives (essentially brakes) into second gear and as a result, I've been taking over and shifting myself at ~3-4k RPM.

My car still makes weird noises and it seems the car is trying to avoid doing that by shifting at 3k+ RPM while in Drive which reduces the slippage at the cost of fuel mileage. But if I'm in gears 2, 4, or 6 and at 1.5-2k RPM I can hear an audible click-click-click-click (granted, it sounds different in gear 6 than in 2 or 4) from my car until I hit 2k RPM. I don't think I should have to monitor which gears I'm in and/or drive in sport mode 24/7 to avoid these issues I'm having. Not that that even eliminates them, it really just makes them less noticeable.

I swear, I'll post that video tonight, weather permitting.

EDIT: [Click me to hear 1st to 2nd gear clutch slippage!]
