My cursor height is stuck at what appears to be the max height of the line and its padding/margin, nor does it blink anymore. Screenshot. What settings should I look at to get this sorted out?
Search in the left side of the Settings window for caret. That should get you to the right group of settings. I have the following set:
// These settings control the size of the caret
"caret_extra_bottom": 0,
"caret_extra_top": 0,
"caret_extra_width": 0,
// Valid values are "smooth", "phase", "blink" and "solid". Previous
// versions of Sublime Text used "smooth" by default.
"caret_style": "smooth"
and it looks pretty similar to ST3.
