Bug 639

Summary: Async blit function cannot enable in x11 driver
Product: SDL Reporter: gatekeeper <gkmail>
Component: videoAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED WONTFIX QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 Keywords: target-1.2.14
Version: 1.2.13   
Hardware: x86

Description gatekeeper 2008-11-06 19:22:50 UTC 
I tried to enable async blit function in x11 driver. The video surface's SDL_ASYNCBLIT flag is set, but I found the the driver is not in async blit mode.
    In file "SDL_x11video.c", the function "X11_SetVideoMode" only records SDL_RESIZABLE and SDL_NOFRAME flags in the surface structure. In file "SDL_x11image.c", function "X11_NormalUpdate" and "X11_MITSHMUpdate" check the SDL_VideoSurface's SDL_ASYNCBLIT flag to enable async blit. It is always false.
    Is it a bug?

Tagging this bug with "target-1.2.14" so we can try to resolve it for SDL 1.2.14.

Please note that we may choose to resolve it as WONTFIX. This tag is largely so we have a comprehensive wishlist of bugs to examine for 1.2.14 (and so we can close bugs that we'll never fix, rather than have them live forever in Bugzilla).

The ASYNCBLIT functionality caused issues with certain X servers and is no longer supported.
