How to prevent Visual Studio Code from opening an extra blank window?

+4
−0

When I run code . in a directory, Visual Studio Code opens two windows. The first is empty, the second shows directory I was in as expected.

I checked ~/.config/VSCode/Workspaces and there is only one in there for a different folder, so that can't be it.

I found a bug about this https://github.com/microsoft/vscode/issues/128175 but that's apparently fixed in 2021, so that wouldn't be it either. My VSC version was 1.77.3 - after updating to 1.79.0 the issue persists.

How can I figure out why VS Code is opening two windows and stop it?

I was able to fix this by deleting the ~/.config/VSCode/Workspaces folder.


To figure this out, I:

  • Backed up my VSCode folder to /var/tmp
  • Deleted ~/.config/VSCode, after this VS Code stopped opening two windows (and created a lot of new files in VSCode/)
  • Used fd to make a list of all files in /var/tmp/VSCode and ~/.config/VSCode/.
  • Used comm to print only filenames unique to the first one.

A lot of these were cache paths, so I decided to start deleting them one by one to see what would fix the issue. As luck would have it, the first one I tried was Workspaces, which did fix it.

My Workspaces contained a single JSON, which had two elements in the folders key. Deleting these didn't seem to help, but deleting the file did.

I've not seen the problem myself, but I did find a mention of the "workbench.editor.enablePreview" setting possibly influencing this. Can you try setting this to false, and see if it makes a difference?

Hmm... That unfortunately didn't change anything, I tried both true and false. It wasn't set before. (1 comment)
