MAC: Smooth window resizing causes window managers not to be able to resize vscode

[patrickhuijten]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.74.0 (Universal)
• OS Version: MacOS Monterrey 12.5.1 (21G83)

While using a window manager on Mac (Mosaic), I'm not able to resize / place the vscode window on the designated location on the screen.

This is relatively new behavior, can confirm this was not an issue prior to release 1.72.1. I believe this release https://github.com/microsoft/vscode/releases/tag/1.72.1 started this bug. vs code is the only application I know of that has this issue.

I included a screen recording showing the problem.

Steps to Reproduce:

1. Using a window manager (mosaic), drag and drop vscode into any of the resizing blocks.

Mosaic requires a purchase, is there a repro with other open source window managers ?

In your demo, you seem to using native titlebar. Does the issue repro when launching with "window.titleBarStyle": "custom" ?

Hi @deepak1556, I was unable to reproduce it with a free alternative from the apple store (Magnet).

Setting "window.titleBarStyle": "custom" was not successful either.

Normally I would approach the developer of Mosaic myself but it's only vs code that stands out here, every other app I know of (30+) work just fine. Even vs code used to work like any other app, hence this bug report.

Mosaic does have a 7 day free trial if that's of any help: https://www.lightpillar.com/mosaic.html

I actually went for that but I just get pop-up that trial is expired on starting the application :(

I have an idea what might have caused this issue in the runtime, Can you maybe help with confirming the issue by following the steps below which requires running VSCode from source.

* Ensure build pre-requisites are available for your platform https://github.com/microsoft/vscode/wiki/How-to-Contribute#prerequisites
* git clone https://github.com/microsoft/vscode
* cd vscode
* yarn
* yarn compile
* ./scripts/code.sh

If the above steps are difficult to attempt now, I will try to provide a custom build later this week to verify.

Thanks for the update. Will give this a try and get back to you 😄

Hi @deepak1556, sorry for the long wait. Happy new year by the way! 🎆

I followed your steps and I can confirm that running with Code - OSS from source I can resize/reposition windows just fine with Mosaic.

Happy new year :) and Thanks for confirming.

As part of an accessibility experiment we disabled the AXManualAccessibility attribute in the runtime which looks like the Mosaic window manager relies on.
