  • VSCode Version: Code 1.14.1 (2648980, 2017-07-13T19:12:01.887Z)
  • OS Version: Linux x64 4.10.0-19-generic
  • Extensions: none

Steps to Reproduce:

  1. Open a file, and put the cursor anywhere.
  2. Watch CPU usage while the cursor blinks
  3. The cursor stops blinking after ~10 seconds, notice how the CPU usage lowered by ~15%
  4. Move the cursor again, it starts blinking, and CPU usage goes up again by ~15%.

I use the phased cursor blink setting.

@ExecThTs for phased style blinking cursor, we use javascript to mimic the bezier curve which consumes so much CPU, you can see our detailed description in #22900 (comment) .

Right now due to Chromium's animation bug, this is our best solution.
