The very first time i noticed something was up, it was when i was accelerating in third gear and the car seemed to hit a wall (both in terms of physical acceleration and the revs ceasing to climb), but this only happened once or twice until i noticed the issue getting worse and begin to replicate what is shown in the video on later test drives. The only explanation i can think of is that when i first noticed the problem (i.e. just before i first posted), the clutch was maybe juuust teetering on the edge of slipping/catching at really high RPMs, and it only began to really slip after I had let the heat build up after a longer drive.

I'm hesitant to say that the issue i first described is completely unrelated, as that would be quite the coincidence timing-wise. It doesn't seem to be happening anymore, but i'll definitely be keeping an eye out to see if it happens again.
