Seems to be a specific technique in the svg, not all svg's are rendered
incorrectly, not sure if this is os related any way starts with versions
higher than 2.30.12.0 (32bit)
example render issue
https://thrive4.github.io/byexample/sdlbroken.jpg
correct display
https://thrive4.github.io/byexample/sdlnotbroken.jpg
technique:
background_surface = IMG_LoadTexture(renderer, backgroundimage)
SDL_RenderCopyEx(renderer, background_surface, null, @srcrect, rotateangle, null, rotateimage)
tested:
on windows 10 and windows 7
with:
SDL2_image-2.8.5-win32-x86
SDL2_image-2.8.6-win32-x86
SDL2_image-2.8.8-win32-x86
and:
SDL2-2.30.12-win32-x86
SDL2-2.32.2-win32-x86
Note: think it is the main sdl2 dll the older 2.30.12.0 sdl2 dll renders
the svg correctly with sdl2_image 2.8.5 ~ 2.8.8 but I am speculating.
svg:
