We are currently migrating Bugzilla to GitHub issues.
Any changes made to the bug tracker now will be lost, so please do not post new bugs or make changes to them.
When we're done, all bug URLs will redirect to their equivalent location on the new bug tracker.

(Sorry if you get a lot of copies of this email, we're touching dozens of bug reports right now.)

Tagging a bunch of bugs as target-2.0.0, Priority 2.

This means we're in the final stretch for an official SDL 2.0.0 release! These are the bugs we really want to fix before shipping if humanly possible.

That being said, we don't promise to fix them because of this tag, we just want to make sure we don't forget to deal with them before we bless a final 2.0.0 release, and generally be organized about what we're aiming to ship.

Hopefully you'll hear more about this bug soon. If you have more information (including "this got fixed at some point, nevermind"), we would love to have you come add more information to the bug report when you have a moment.

Thanks!

I believe the position is fixed from #2421


but there is still a weird behaviour with the renderer software:
when rotated +90 or -90, some transparent lines appears, though there is no Alpha or ColorKey.

if you set a dummy colorkey, it will remove the line ...
if you set a some alpha mod, the +90/-90 get transparent but not the 0/180  ...









   SDL_Surface *surf = IMG_Load_RW(SDL_RWFromMem((void*)street_vert_jpg, sizeof(street_vert_jpg)), 0); 
   SDL_PixelFormat  *pixel_format = SDL_AllocFormat(SDL_PIXELFORMAT_RGB888);
   SDL_Surface *surf2 = SDL_ConvertSurface(surf, pixel_format, 0); 
   SDL_SetColorKey(surf2, SDL_FALSE, 0); 
//   SDL_SetColorKey(surf2, SDL_TRUE, 999);// a colorkey would remove the lines ...
   SDL_SetSurfaceBlendMode(surf2, SDL_BLENDMODE_NONE);
//   SDL_SetSurfaceAlphaMod(surf2, 0); // setting alpha mod, make +90&-90 transparent
   SDL_Texture *tex = SDL_CreateTextureFromSurface(renderer, surf2);

Plain black (0/0/0) was interpreted as a ColorKey, because SDL gfx rotate function uses former SDL-1.2 style to interpret SDL_Surface flags.

Some patch ...

oops wrong patch, the error was a little after: background surface had always the ColorKey set.
