Same here : creating 2 SFML canvas in a wxWidgets application results in the same problem. Each canvas shows when alone, but the second does not when together. It seems not to refresh, as it sometimes shows other parts of the application in the canvas (title, the other canvas, menus...).
In Windows 7, the same code works well.

Here is a piece of C++ code which may help in solving the bug :

///////////////////////////////////////////////////////////

////////////
Class Game :
////////////

Game::Game() : renderWindow(sf::VideoMode(800,600),"")
...

void Game::inGame()
{
...
testMap.createRender(this);
...
}

void Game::showSprite(sf::Sprite& sprite)
{
    renderWindow.draw(sprite);
}

///////////
Class Map :
///////////

void Map::createRender(Game* parent)
{
...
parent->showSprite(tilesFiles[nbTileset]);  //tilesFiles is an sfml sprite
...
}

///////////////////////////////////////////////////////////

With this code, the same garbage and errors happen.

//// I'm sorry for my english ////

I'm sorry, forgot to say that the pointer is the cause of the bug. Directly accessing the Game class with a global variable works perfectly.

//// I'm sorry for my english ////

I apologize, the bug was not comming from the pointer, but from fact I was loading textures before creating the window. Really sorry.

The bug is still present for me when opening two SFML windows, but dmesg output changed :

Opening the windows in different threads works.

Many thanks for your work.

I can confirm this bug with the shader example of SFML 2.0 RC, with an Evergreen gpu (5850) and Mesa 8.0.4. Rendering is messed up and there's a lot of "radeon: The kernel rejected CS, see dmesg for more information.".

Thanks by advance.

Some further data points:

- There are no obvious problems when running the test cases with software rendering, only with r600g.

- I tried to use apitrace to capture this bug, but in both cases (shader example and the one with two windows) replaying the trace works fine, with no rejected CS.

same problem here when trying to run dungeon siege 2 via wine, intro plays fine and then hangs , found a radeon problem to be the cause.

Keep in mind that you can get these errors does not necessarily indicate the same problem, so it's probably not a good idea to make this bug a dumping ground for rejected CS.

I tried the demo of the game but couldn't reproduce this. It seems to be working fine both with 8.0.4 and with git master.

to be more precise its the dungeon siege 2 broken world  extension afther running the video config feature from the game. I will try to reinstall wine and the game to give the exact steps i followed.

Are you guys talking about the same sample causing the bug? If not, it's probably different bugs.

I can confirm this bug is still there on Evergreen (Radeon 6320 Wrestler, Fusion APU) with SFML shader example and with Mesa 9.0.1. Error message log is unchanged.
