Resize window problem

SDL Development
1

Hello,

I have recently been upgrading a little game of mine to use OpenGL,
instead of just SDL for graphics. I have a function which resizes the
window, by calling SDL_SetVideoMode, but when I use it, each time it
leaks a lot of memory, proportional to the size that I am resizing to.
Why does this happen? Isn’t SDL_SetVideoMode supposed to release the
old screen surface? After resizing the window this way, I reload my
textures and OpenGL attributes and stuff, and there are no memory
leaks there.

Thanks

are you freeing the old textures before you reload them?On 12 May 2010 01:21, Nikola Whallon <alokin.nollahwe at gmail.com> wrote:

Yes. I have tested that code separately too (reinitializing the OpenGL
stuff and textures without resizing the screen), and do not have any
leaks there.On Wed, May 12, 2010 at 3:42 PM, Kenneth Bull wrote:

Did you try using the display quit, then init again as well?

Yes, I run:

SDL_QuitSubSystem(SDL_INIT_VIDEO);
SDL_InitSubSystem(SDL_INIT_VIDEO);
screen = SDL_SetVideoMode(xrez, yrez 16, SDL_OpenGL);

etc

in my resize window function.On Thu, May 13, 2010 at 11:12 AM, Ren? Dudfield wrote:
