Very glitching resizing with Quick applications with some backends

When trying to resize Qt Quick applications, the process is very "glitchy". See attached video.

There were also some artefacts the recording doesn't pick, in the menu bar.

I forced backends using:

QQuickWindow::setGraphicsApi(QSGRendererInterface::/*backend*/);

And:

• It works fine with either ::Software, ::OpenGL, ::OpenGLRhi;
• It's glitchy with either ::Direct3D11Rhi, ::VulkanRhi;
• Can't test ::MetalRhi because I don't own a mac.

The video depicts the "Qt Quick Controls - Text Editor" example, but it happens with any Qt Quick application.
