Rendering of multiple instances of a framebuffer object leads to degraded render performance on Wayland platform. The similar effect does not happen on other QPA's like xcb or eglfs.
Steps to reproduce:
- Run the compositor in attached example project qmlscene compositor.qml
- Execute the application with Wayland ./qquickviewcomparison -platform wayland
- The animation runs smoothly on three framebuffer object.
- The animation performance is heavily impaired and frame rate goes down to 5-8FPS.
