xcb: Window opacity might not be immediately set

    Details

    • Platform/s:
      Linux/X11

      Description

      When QWidget::setWindowOpacity is set for a window, it might randomly still be painted at 100% opacity for a frame. Can be reproduced on Ubuntu and RHEL with attached example.

      It looks like moving the setOpacity call in qxcbwindow.cpp to right after xcb_create_window fixes this at least.
