Title: Window only updates when mouse is moved over it.
Post by: Rubenknex on April 16, 2011, 10:52:28 am

I just switched to Ubuntu and tried using SFML, however my RenderWindow only updates when I move the mouse cursor over it.

I use the code from the tutorial about Sprites and move the sprite by a tiny amount each frame. If I move the mouse for a few seconds the window keeps updating after I stop moving it, but after a few seconds the window stops updating.

Code: [Select]


#include <SFML/Graphics.hpp>
 
 int main()
 {
     sf::RenderWindow App(sf::VideoMode(800, 600), "SFML window");

     sf::Image Image;
     Image.LoadFromFile("data/circle.png");
     sf::Sprite Sprite(Image);

     while (App.IsOpened())
     {
         sf::Event event;
         while (App.GetEvent(event))
         {
             if (event.Type == sf::Event::Closed)
                 App.Close();
         }

         sprite.Move(20 * App.GetFrameTime(), 0);
 
         // Clear screen
         App.Clear();
 
         App.Draw(sprite);
 
         // Update the window
         App.Display();
     }
 
     return 0;
 }

Are you using a compositor window manager such as Compiz?

I think I'm using metacity with compositing enabled, but I'm not too sure as I've just started using Ubuntu.

You should try to disable it (if you find how to) and see if it still happens.

I succeeded in disabling compositing and the problem still remains  :(.

Never mind... I made a stupid mistake, I quickly wrote the event loop and never looked at it again, but I accidentally included the updating and rendering inside it. I feel stupid  :x.
