Title bar too big in some screens, does not scale with zoom

[juanep97]

In Ubuntu 24.04 under Wayland, in my main hidpi monitor, the title bar size is correct. When I connect a second (bigger) monitor, and other applications are moved over to the second screen, they are correctly automatically resized down (their size in pixel decreased, so their physical size stays more or less constant). VSCode is not resized, and therefore appears too big. I can zoom out inside VSCode so the size is corrected, but this does not affect the title bar, which, as can be seen in the image, stays way too big compared to other windows (next to a terminal in the example).

There could be two ways of fixing this behavior: allow zooming out the title bar, and/or make vscode correctly resize when moving to a monitor of different size. Ideally both.

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

• VS Code Version: 1.96.0
• OS Version: Ubuntu 24.04 LTS

Steps to Reproduce:

1. Using vscode in Ubuntu (Wayland)
2. Use custom title bar

I found out vscode is correctly scaled between monitors at different scalings when Wayland is enabled (code --enable-features=UseOzonePlatform,WaylandWindowDecorations --ozone-platform-hint=auto). Maybe this could be the default.

@deepak1556 do you have context on this?

[deepak1556]

Seems like an issue specific to xwayland, definitely a runtime issue. We would need to create a minimal repro with WCO and file an issue at https://github.com/electron/electron/issues

For using native wayland as default, please follow #207033 which will offer some sort of persistent setting in the application.
