Empty windows with SDL2 renderer on macOS #5931
Description
Version/Branch of Dear ImGui:
Version: 1.89.1
Branch: master
Back-end/Renderer/Compiler/OS
Back-ends: imgui_impl_sdl.h, imgui_impl_sdlrenderer.h; SDL2 using Metal
Compiler: Apple clang 14.0.0 (am64-apple-darwin22.1.0)
Operating System: macOS Ventura 13.0
My Issue/Question:
I'm trying to render the demo window and one additional window. The window frames are both shown but only the additional window has a title and both of the windows are completely empty. The mouse also seems to be strangely offset. At first I thought this might somehow be a font issue because of the missing text but adding a custom font made no difference.

Standalone, minimal, complete and verifiable example:
(error handling omitted for brevity)
int main(it argc, char* argv[]) {
// Create SDL window and renderer
SDL_Init(SDL_INIT_EVERYTHING);
window = SDL_CreateWindow("Hello World", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 480, SDL_WINDOW_RESIZABLE | SDL_WINDOW_ALLOW_HIGHDPI | SDL_WINDOW_METAL);
renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
// ImGui Init
IMGUI_CHECKVERSION();
ImGui::CreateContext();
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontDefault();
ImGui_ImplSDL2_InitForSDLRenderer(window, renderer);
ImGui_ImplSDLRenderer_Init(renderer);
ImGui::StyleColorsDark();
SDL_Event evt;
while(true) {
while(SDL_PollEvent(&evt)) {
ImGui_ImplSDL2_ProcessEvent(&evt);
}
ImGui_ImplSDLRenderer_NewFrame();
ImGui_ImplSDL2_NewFrame();
ImGui::NewFrame();
ImGui::ShowDemoWindow();
ImGui::Begin("Debug");
ImGui::Text("Hello World");
ImGui::End();
ImGui::Render();
SDL_SetRenderDrawColor(renderer, 0x0, 0x0, 0x0, 0xFF);
SDL_RenderClear(renderer);
ImGui_ImplSDLRenderer_RenderDrawData(ImGui::GetDrawData());
SDL_RenderPresent(renderer);
}
}
