Bug 3707

Summary: YUV textures problem with Software rendering, x86
Product: SDL Reporter: Egor Pavlov <egor-pvl>
Component: renderAssignee: Sam Lantinga <slouken>
Status: RESOLVED DUPLICATE QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: 2.0.5   
Hardware: x86   
OS: Windows 10   

Description Egor Pavlov 2017-07-21 01:23:43 UTC 
YUV textures doesn't displayed in Software rendering mode on Win32(x86).
Renderer creation code:
SDL_Renderer* renderer = SDL_CreateRenderer(screen, -1, SDL_RENDERER_SOFTWARE);
On x64 this code work fine.

Can be fixed on x86:
SDL_Renderer* renderer = SDL_CreateRenderer(screen, 0, SDL_RENDERER_SOFTWARE);

This bug doesn't affected on RGBA textures.

Can you provide sample code?
Comment 3 Sam Lantinga 2017-08-12 22:08:34 UTC 
I believe this was caused by MMX assembly, which is now disabled while we figure out how to fix it for all compilers.

Thanks!
