xdg-shell unstable v5 (eventually v6 when maximize/fullscreen is implemented).
Description
Only xdg_shell has ack_configure, so wl_shell and ivi_application are not affected.
xdg-shell v6 is currently unaffected, since maximize/fullscreen is not implemented. Had it been implemented we would have faced the same issue.
On some compositors, this causes a protocol error (terminates the application).
Steps to reproduce:
1. Start a Qt application with QT_WAYLAND_SHELL_INTEGRATION=xdg-shell-v5 set
2. Toggle fullscreen
Some compositors will report a protocol errors, on others, you can observe the logs with WAYLAND_DEBUG=1 set and see that old buffers are committed after ack_configure.
