Hi have this strange problem under Windows : whenever I resize the window or switch resolution, the OpenGL context is lost (textures, options & flags ...). Is there a way of avoiding this problem ?

Anybody has a solution to this problem ?

I use GLFW and I can resize windows without losing. But when video mode is changed, you need to reload resources. I don''t know if there''s solution.

For window changing color depth there''s not. Windows will not allow to change the pixel format so you will have to blow up teh window (and the render context) and restart everything.

Changing resolution is probably possible without destroying the window but I am quite sure MSDN says it is bad. I actually think it should work anyway.

For window being resized, this is absolutely wrong. Check out your messageproc code. BTW, consider making the window non resizeable. This would be bad but it is not usually a problem for 3d games.

Using SDL+OpenGL, whenever I resize a window, the textures are lost. Maybe my window-resize-code is bad...

I started coding things to reload automatically all textures when changing video mode/resizing window. Seems to work so far...

Thanx anyway !
