I have a rather naive question... Recently I brought down the newest version of xloadimage (hot stuff, I had more fun that I have had in weeks). For something really *cool* to do, I made the red dragon gif image my root background -- looks great. But I am puzzled by something. When I move, let's say an icon, it disappears and reappears with no perceptible difference in reponse over what it would have done with a bland background. When I uniconfy the icon, however, it slowly erases the icon from the bottom and when it is done is pops up the window as handy as you please. I am using mwm on a SPARC SunOS 4.1. Could someone explain to me the difference? +---------+ | Coral | |@@@@@*@**| |@@*@@**@@| Don Dewar |*@@**@@@@| Coral Network Corporation, Marlborough, MA |@***@@@@@| Internet: don@coral.com |@@**@@@@@| Phone: (508) 460-6010 |*********| Fax: (508) 481-6258 |Networks | +---------+

Using xloadimage to put a large picture in your root creates a large pixmap which the server must page in whenever it needs to expose more of the root (as when you unmap or move a window). How long it takes is highly non-deterministic, as it depends on many factors such as how much is paged out and how many other processes are running at the moment. Perhaps the slowness you see when deiconifying a window is due to the server competing for resources with the application, which must now process its expose event(s). < Stephen MIT X Consortium
