Welcome

  • Yes, I'm using the latest major release or the current development version. These are the only supported versions.
  • Yes, I've searched similar issues and discussions on GitHub and didn't find any.

Current Behavior

When opening multiple VSCode in tabbed mode, the ones that are not foccussed fail to load with Unable to figure out browser width and height: Error: Unable to figure out browser width and height. Please see microsoft/vscode#224724 for more details.

Just wanted to ask if you have an idea why this might be. Is it that VSCode does not handle this situation correctly and it should get fixed there, or is it that i3wm is not providing the needed information? Thank you.

Expected Behavior

VSCode/Electron should be able to start normal even if not currently focused.

Reproduction Instructions

Please see microsoft/vscode#224724 for reproduction Instructions.

Here is a logfile:

https://logs.i3wm.org/logs/6266537128230912.bz2

Each window where it just says WM_NAME changed to "Visual Studio Code", without further updating it, is a misbehaving one. The one with _NET_WM_NAME changed to "client.py - sockserver - Visual Studio Code" is the one that got focused, and renders correctly.

Note that when I open VSCode in splitted mode (so each window gets focussed), the startup works fine. It's just when VSCode opens multiple windows (last sessions) in tabbed mode, that those which don't receive focus during startup fail to render and error out with Unable to figure out browser width and height: Error: Unable to figure out browser width and height
