Version/Branch of Dear ImGui:
Version 1.91.9 WIP, Branch: master.
Back-ends:
imgui_impl_sdl3.cpp + imgui_impl_vulkan.cpp
Compiler, OS:
Windows 11 + MSVC && MacOS 13 Ventura + Apple Clang
Full config/build information:
No response
Details:
upon calling
ImGui_ImplVulkan_Init, there is a segmentation fault inImGui_ImplVulkan_LoadDynamicRenderingFunctions, due to it callingImGui_ImplVulkan_GetBackendData, which gets the value ofImGui::GetIO().BackendRendererUserData. The problem arises in the fact that this isn't set until line1143ofimgui_impl_vulkan.cpp, whileImGui_ImplVulkan_LoadDynamicRenderingFunctionsis called before this, at line1128. On top of this, the value cannot even be set manually, as imgui will assert, claiming that the renderer backend has already been initialized.Proposed solution: Move lines
1124-1134(the if statement containing the check for dynamic rendering) after the value forImGui::GetIO().BackendRendererUserDatais set.Screenshots/Video:
No response
