Description Martin Gerhardy 2015-12-01 15:50:48 UTC 
As can be seen in the attached videos, the renderer that rotates the scene weird is basically the opengles2 renderer on windows (works fine on linux btw). If i switch the renderer to direct3d with the renderer hint, everything works fine again (same for opengl) - as can be seen in the videos.

Comment 4 Martin Gerhardy 2015-12-30 18:51:02 UTC 
I was now also able to reproduce the issue with linux opengles2 renderer
Comment 5 Martin Gerhardy 2015-12-30 19:08:35 UTC 
The error is most likely in GLES2_RenderCopyEx. I'm using a rotation per sprite (for the font characters) - but instead the whole scene is rotated. Another explanation is that the shaders from SDL_shaders_gles2.c are doing the rotation in a different way than all the other renderers.

I tried with this test case and could not reproduce it. Does this issue still exist ? 
I saw no modification to GLES2_RenderCopyEx in the meantimes though

As tested, this is working to me. 
Please re-opening if you have still the issue!
