This just started happening to me yesterday and up until then it wasn't a problem. Maybe it has something to do with the VS code update, but when fold fix is enabled, when I start visual line mode, it won't let me exceed 3 vertical jumps when I hit 'k'.
I've commented out all other key-bindings and the problem persists, but when I comment out fold fix, it starts working.
I also noticed, probably the same bug, but if I use '{' to jump in visual line mode, then press 'j' in attempt to go down to where I want, it brings me 1 lines below the initial starting point.
Just wanted to add a piece of information for anyone looking into this. Experiencing the same issue as listed by @JoshTRN.
Just noticed attempting a visual jump with k with a number ie 10k will actually work but only once. Past that just returns to the initial line.
Exactly the same problem.
