Bug 1958

Summary: Cocoa SwapWindow doesn't swap the specified window
Product: SDL Reporter: Ryan C. Gordon <icculus>
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: HG 2.0   
Hardware: All   
OS: Mac OS X (All)   

Description Ryan C. Gordon 2013-07-11 12:41:26 UTC 
We have this in Cocoa_GL_SwapWindow()...

    /* FIXME: Do we need to get the context for the window? */
    [[NSOpenGLContext currentContext] flushBuffer];

...which means if the current GL context is not the one in (window), we swap a different one than requested.

Right now, we don't store information about which context is assigned to which window, and the OS doesn't give you a way to retrieve it from an NSView. We would have to track this per-window during SDL_GL_MakeCurrent() (and SDL_GL_CreateContext) calls.

--ryan.
