Flickering on Resize

SUMMARY
When resizing a Kirigami App, the app flickers, with the content of the app seemingly moving into a region outside the frame of the window.

STEPS TO REPRODUCE
Resize the app

OBSERVED RESULT
Notice the black bar appearing on resize in the video above, as well as the visible flickering of application controls.

EXPECTED RESULT
Seamless resizing, as happens with QtWidgets.

SOFTWARE/OS VERSIONS
Kirigami master
Application running on wayland w/ Qt 6

It's not specifically a Kirigami bug per se. It's about interaction between Qt, 3D acceleration (OpenGL/Vulkan/etc), video drivers and everything elsewhere. Search Google for "qtquick resize window flickering" and you'll find a lot of material. You can see it even in the Qt Group's official announcement video, around 1:00 (start of the second minute): https://www.youtube.com/watch?v=f8lc-cRdDKE
