Repeatedly opening and closing the terminal causes VS Code to freeze

[mihaiconstantin]

Issue Type: Performance Issue

I noticed that, with the most recent update, after I open and close the terminal several times, VS Code hangs (i.e., see this brief video: https://youtu.be/uwTt3cvETAc). Additionally, it seems to hog the CPU resources by spawning many consoles (i.e., see this screenshot: https://imgur.com/a/UQZ2eRJ).

I tried a clean install and disabled all the extensions, however, the issue still persists. Any clue what is going on?

Update

I removed the following lines from my user settings (i.e., the cmder_mini console):

"terminal.integrated.shell.windows": "C:\\Windows\\System32\\cmd.exe",
"terminal.integrated.shellArgs.windows": ["/k", "C:\\PROGRA~1\\cmder_mini\\vscode.bat"],

Regardless, the issue still persists with the default PowerShell terminal.

In case it helps, these are my user settings:
