    Details

    • Platform/s:
      Linux/X11, Windows

      Description

      To reproduce, run attached example on Linux (issue is not limited to Linux though) and wait. Translucent background should be set, but it keeps old setting. QWidgetPrivate::updateIsTranslucent() only sets requested format for the window, but that is not used until window would be recreated (destroy();create();show();).
