I can reproduce this and seems like the bug has existed for a while (at least since snapshot-151). :term does not exhibit this behavior. I will need to double check this doesn't happen in regular gVim first.

for-coursera commented 4 years ago

May be somehow related:

  1. Run mvim --clean
  2. Enter shell by executing :shell command, the cursor is there
  3. Exit shell
  4. Disable guicursor blinking: :set guicursor+=a:blinkon0
  5. Enter shell by executing :shell command, the cursor is no longer visible
  1. But if we exit shell
  2. :set guioptions+=!
  3. And then enter shell again by executing :shell command, the cursor is visible again.
