Description
I'm trying to create a very simple wayland compositor using the examples found here, like this:
import QtQuick 2.12 import QtQuick.Window 2.2 import QtWayland.Compositor 1.3 WaylandCompositor { id: wlcompositor WaylandOutput { compositor: wlcompositor window: Window { width: 800 height: 480 visible: true title: wlcompositor.socketName Grid { anchors.fill: parent anchors.margins: 100 columns: 2 Repeater { model: shellSurfaces ShellSurfaceItem { id: shellSurfaceItem autoCreatePopupItems: true shellSurface: modelData onSurfaceDestroyed: shellSurfaces.remove(index) } } } } } ListModel { id: shellSurfaces } XdgShell { onToplevelCreated: shellSurfaces.append({shellSurface: xdgSurface}) } }
And then I'm creating a separate client app that just creates a couple Rectangles as a test.
import QtQuick 2.12 import QtQuick.Window 2.12 Window { id: window visible: true width: 200 height: 200 Rectangle { anchors.fill: parent color: "green" Rectangle { x: 10 y: 10 width: 100 height: 100 color: "blue" } } }
Everything seems simple and straightforward. But when I run it on my Pi4 (using the -platform wayland flag), the client gets crazy distortion, like this: 
I'm testing it with Boot2Qt with versions 5.14.2 and 5.15.0 with the same results. There are no errors on the console. Nothing that indicates anything is wrong except that it looks awful.
I did notice that if I use weston as my compositor instead of QtWayland, then the app looks perfect. So that makes me think there's something wrong with WaylandCompositor. But my search of google found nobody else complaining of the same thing.
