Type: Bug

Behaviour

When a debug was performed, the cursor kept blinking once the mouse cursor moved. And once I left clicked the mouse, the text cursor would always pop to the end of the clicked line.

Steps to reproduce:

  1. Debug a Python Program.
  2. Once the debug starts, when the color theme changes, click on a line.

Diagnostic data

launch.json configuration 

This file doesn't exist in the current working directory.

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
