VCS settings menu showing up as black

[twaritwaikar]

Godot version

4.0.beta1

System information

Windows 10, Vulkan, GeForce GTX 1060 6GB DCH driver 511.79

Issue description

The VCS settings menu shows up as completely black.

There are no directly related errors in the console, except for some API version mismatches, which is expected since this plugin is using an older version of the GDExtension API.

Steps to reproduce

1. Open the repro project
2. Click on Project > Version Control > Version Control Settings
3. See a blacked out window

Workaround steps:

1. After the blacked out window has appeared, go back to the editor window
2. Click on Project > Version Control > Version Control Settings again (it wouldn't give a visual feedback of the popup getting selected)
3. Switch to the earlier blacked out window
4. Notice that it is now showing up as expected

Minimal reproduction project

Does appear on a fresh new project

Also, there is a weird flicker in the window that is triggered when the mouse is on top of it or when the pointer leaves the window boundaries

Can you reproduce this after enabling Single Window Mode in the Editor Settings then restarting the editor?

[twaritwaikar]

Enabling single window mode helps keep the rendering as expected, however, the window itself is now placed on the top left such that the top bar is covered by the Win32 window's title bar

There is a sliver of space where I can click and drag the popup window to its usual place i.e. the centre of the screen
