New Terminal output adding spaces and % resulting in cut off when activating Python environments (venv)

[slimsnerdy]

Does this issue occur when all extensions are disabled?: Yes/No
Yes (only Python/Pylance installed since needed)

• VS Code Version: 1.81.1
• OS Version: macOS Ventura 13.5.1

Steps to Reproduce:

1. Open Command Palette --> Python: Create Environment --> Venv --> Python (I chose Python 3.10.12 64-bit) --> requirements.txt (leave unchecked) click OK

2. Now create a new terminal; this is the strange part.. Sometimes it will add a % and a whole bunch of spaces when "activating" the environment.. look at the line with source.. the_slim_fatty_p% rod/.venv/bin/activate
   That is actually a bunch of spaces. Right click the Terminal window and "Toggle Size to Content Width" to see.

Sometimes creating a new terminal does not do this behavior and no spaces are added and that weird %.
This happens on new machines too. New projects from scratch. Python and macOS only tested.
Very random behavior; quickest way to test is click the plus icon on the bottom right to open new terminals so it activates in rapid succession and most of the time it actually does not add the spaces to the output. But every 4 or 5 clicks it does.. I have no idea.

CORRECT BEHAVIOR:

@meganrogge We simply send the command source <activate> to VS Code, how it appears in terminal is not something we have control over.

• @slimsnerdy Can you provide the Python logs?

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

hmm output is actually.. empty?

I see, can you send a screenshot of the Python output channel? Try reloading/reopening VS Code.
