Mirrored screen output

Executing testrendercopyex on some devices - tested on Galaxy Tab 2 10.1 - Cyanogenmod 10.1 (~Android 4.2.2) draws a mirrored screen output.

I could only test it on landscape mode until jet.
See attachment for screen output.
Comment 1 Daniel Knobe 2013-11-23 11:47:03 UTC 
I have did one more test to see where the problem come from.

If I comment the following code:
...
    //target = SDL_CreateTexture(s->renderer, SDL_PIXELFORMAT_ARGB8888, SDL_TEXTUREACCESS_TARGET, viewport.w, viewport.h);
    //SDL_SetRenderTarget(s->renderer, target);
...
    //SDL_SetRenderTarget(s->renderer, NULL);
    //SDL_RenderCopy(s->renderer, target, NULL, NULL);
    //SDL_DestroyTexture(target);

Everything works on the tablet, too. So switching on a texture as the rendering target and that drawing it on the screen leads to that problem on this device.

Is this the opengles 2 renderer? Any other info you can provide? Do you see it on other devices?
Comment 3 Sam Lantinga 2013-11-27 08:33:20 UTC 
Can you try the latest SDL snapshot?

Thanks!

Sorry for the late answer.

Yes the actual version of SDL fixes the problem!

Thanks!
