Bug 1851

Summary: SDL_render_gles.c: useDrawTexture does not play well with SDL_RenderSetLogicalSize()/SDL_RenderSetScale()
Product: SDL Reporter: Pallav Nawani <pallavnawani>
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED DUPLICATE QA Contact: Sam Lantinga <slouken>
Severity: major    
Priority: P2    
Version: HG 2.0   
Hardware: iPhone/iPod touch   
OS: iOS (All)   

Description Pallav Nawani 2013-05-14 08:23:56 UTC 
The GL ES1 extension GL_OES_draw_texture does not play well with renderer scaling as done by SDL_RenderSetScale(). This is because GL_OES_draw_texture  does a unscaled raw blit, ignoring any scaling.

Fix would be to test for the presence of scaling in GLES_RenderCopy() before using the extension.

Bug is present in Android as well as iOS.
