Is QQuickRhiItem not working well with vulkan?

Hi,

I created a simple QQuickRhiItem example which should display an image.

The issue happens only if I'm using the VK backend (set QSG_RHI_BACKEND=vulkan env variable) and if I change the item size from Main.qml from

        width: 320
        height: 240 

to

        width: 320 * 3
        height: 240 * 3 

The example works great with opengl backend.
