Won't fix since Adobe Flash is non-free software and I rarely use it. When/if other software shows the same problems, I'll investigate further.\r\n\r\nHere's what happens:\r\n\r\n* Suppose you watch a YouTube video using the Flash plugin in Firefox. Now you hit the plugin's \"fullscreen\" button.\r\n* Firefox creates a new window for the plugin.\r\n* The new window issues a ConfigureRequest *before* mapping the window. At that stage, we don't manage the window yet. Thus, we blindly acknowledge the request.\r\n* Next, the new window issues a MapRequest. We now evaluate EWMH hints and make the window fullscreen.\r\n* However, Flash ignores all changes to its window size. There's no way to resize the darn thing. It only uses those values of the reply to the very first ConfigureRequest.\r\n* If you have more than one screen, then the initial ConfigureRequest will use the geometry of the very first screen. Thus, your \"fullscreen\" Flash window will always have that size -- which might be too small or too large if the window is shown on another monitor.\r\n\r\nBy the way, this is broken in dwm, too."}}
