Description
if (gd.isFullScreenSupported()) {
gd.setFullScreenWindow(frame);
}
this code only maximizes window. This issue can be reproduced on a reparenting window manager.
From X11GD_SetFullscreenMode(), awt_GraphicsEnv.c:1793
/*
* Note: the Window passed to this method is typically the "content
* window" of the top-level, but we need the actual shell window for
* the purposes of constructing the XEvent. Therefore, we walk up the
* window hierarchy here to find the true top-level.
*/
But since our frame window is not a direct child of a root window, we sending client event with wrong window.
So we should find another way to determine a "top-level" window.
