   - SDL2: made `ImGui_ImplSDL2_GetContentScaleForWindow()`/`ImGui_ImplSDL2_GetContentScaleForDisplay()`
     helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value
     and this breaks scaling border size. (#9369)
+- Examples:
+  - GLFW+Vulkan, SDL2+Vulkan, SDL3+Vulkan, Win32+Vulkan: reworked to create a descriptor pool with:
+    - IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE.
+    - IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE       descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER.
