dwmapi error

[v71]

Hello this simple code causes the error reported below, what am I doing wrong ? note that this eror appears only in fullscreen mode.

`
// Use OpenGL 3.1 core
// SDL_GL_SetAttribute(SDL_GL_ACCELERATED_VISUAL, 1);

SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 5);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_CORE);

What version of SDL are you using? I believe this is already fixed in the latest version. You might need to grab SDL main code for the fix though.

[v71]

SDL3 version 3.1.8

[slouken]

Please try the latest release:
https://github.com/libsdl-org/SDL/releases/tag/release-3.2.18

[v71]

Ok, will update

[v71]

After having updated to the new libraries i get these errors , only when fullscreen is enabled

Can you step through the SDL code and see where these errors are coming from?

[v71]

The error appears in this line SDL_SetWindowFullscreen(GlWindow, true);
the error persists also with a minimal code to initialize an opengl version trhough sdl

[slouken]

I mean what line inside SDL source code?

[v71]

Will update you , its somehow relate to the dwm api window composition, probably the window asks for some dimensions since it goes fullscreen, and the service denies the request
