I'm unable to compile the latest SDL (directly from the repository) even though I disabled every DirectX option since I don't need DirectX.
I allways het these errors:
D:\DevLibs\SDL\src\render\direct3d\SDL_render_d3d.c:1897:1: error: unknown type name 'IDirect3DDevice9'
D:\DevLibs\SDL\src\render\direct3d\SDL_render_d3d.c:1898:25: error: unknown type name 'SDL_Renderer'

As it turns out, it was impossible to render a texture flipped diagonally (both vertically and horizontally) with one RenderCopyEx call.
With help from #SDL @ freenode, we came up with a fix.

Overview:
SDL_RenderClear is only clearing part of a texture when it is the render target and a different size than the screen.
Steps to Reproduce:
1) This only occurs with the render driver set to direct3d, so: SDL_SetHint(SDL_HINT_RENDER_DRIVER,"direct3d")
Also, my window was 1280x720.
2) Create a texture for a render target with a resolution of 1024x1024:
texture=SDL_CreateTexture(main_window.renderer,SDL_PIXELFORMAT_RGBA8888,SDL_TEXTUREACCESS_TARGET,1024,1024);
SDL_SetTextureBlendMode(texture,SDL_BLENDMODE_BLEND);
3) Target the texture for rendering: SDL_SetRenderTarget(main_window.renderer,texture);
4) Set the draw color to whatever you want (problem occurs with both 0,0,0,0 and 0,0,0,255 among others) and then clear the render target:
SDL_SetRenderDrawColor(main_window.renderer,0,0,0,0);
SDL_RenderClear(main_window.renderer);
Actual Results:
Only about the top 3/4s of the texture gets cleared on calling SDL_RenderClear. The bottom 1/4 or so does not clear.
Expected Results:
Entire render target should be cleared.
Added a reference to SDL_Direct3D9GetAdapterIndex to SDL_test_common.c so SDL will fail to compile if the new symbol isn't included properly.

From Sythical:
Hello, I've created a simple SDL2 application which draws a texture on the screen. The problem I'm having is that if I launch another program which loads the UAC popup or if I lock my PC and then login again, the application stops drawing the texture. I tried adding SDL_Delay(10000) after SDL_RenderPresent(renderer). This made the texture stay on the screen for a little bit but the texture wasn't drawn again after the delay. Here's my code:
#include "SDL.h"
int main(int argc, char *argv[])
{
SDL_Renderer *renderer;
SDL_Window *window;
SDL_Surface *surface;
SDL_Texture *rect_texture;
SDL_Event main_event;
SDL_Rect rect_data;
int enable_vsync = 1;
if(SDL_Init(SDL_INIT_VIDEO) < 0) return 1;
window = SDL_CreateWindow("SDL2 Application", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 600, 600, SDL_WINDOW_RESIZABLE);
renderer = SDL_CreateRenderer(window, -1, enable_vsync ? SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC : SDL_RENDERER_ACCELERATED);
SDL_SetRenderDrawColor(renderer, 20, 20, 30, 255);
surface = SDL_LoadBMP("icon.bmp");
rect_texture = SDL_CreateTextureFromSurface(renderer, surface);
rect_data.w = 32; rect_data.h = 32;
rect_data.x = 300; rect_data.y = 300;
while(main_event.type != SDL_QUIT)
{
SDL_PollEvent(&main_event);
SDL_RenderClear(renderer);
SDL_RenderCopy(renderer, rect_texture, NULL, &rect_data);
SDL_RenderPresent(renderer);
}
SDL_DestroyTexture(rect_texture);
SDL_DestroyRenderer(renderer);
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}
Anisotropic filtering is meant to be used for textures at a stark
angle, not perpendicular to the camera.

SDL_RenderSetClipRect() calls into renderer->UpdateClipRect(renderer).
I am not sure if UpdateClipRect() can point to a number of clip rect update functions, but on my platform it calls D3D_UpdateClipRect().
In that function, the rect to pass to IDirect3DDevice9_SetScissorRect() has it's right field set as:
r.right = rect->w + rect->w;
But actually, this should be:
r.right = rect->x + rect->w;
This lets us change things like this...
if (Failed) {
SDL_SetError("We failed");
return -1;
}
...into this...
if (Failed) {
return SDL_SetError("We failed");
}
Fixes Bugzilla #1778.

I have investigated the warning "Failed loading D3DX9_*.dll" and come up with the enclosed patch (please forward it to relevant SDL2 mailing list/bugtracker).

static void
D3D_DestroyRenderer(SDL_Renderer * renderer)
has a critical problem. It may try to release IDirect3DSurface9 surface pointed
by NULL pointer. That leads to really wierd consequences on my system.
It happens when the previous call to IDirect3D9_CreateDevice() fails leaving
D3D_RenderData::defaultRenderTarget uninitialized.

RenderTarget has to be released before a device reset is done. It's a
D3DPOOL_DEFAULT surface (resides in video memory and have to be recreated).
- Added new SDL_HINT_ALLOW_TOPMOST hint, when set to "0" then never set the topmost bit on a window. Useful when debugging fullscreen issues.
- fixed crash in windows joystick scanning if we failed to load the xinput dll
- added support for SDL_WINDOW_FULLSCREEN_DESKTOP under windows
- synthesize relative mouse movements if directinput fails to send relative moves, happens under virtual box.
