   own render pass. (#3455, #3459) [@FunMiles]
 - Backends: DX12: Clarified that imgui_impl_dx12 can be compiled on 32-bit systems by redefining
   the ImTextureID to be 64-bit (e.g. '#define ImTextureID ImU64' in imconfig.h). (#301)
+- Backends: DX12: Fix debug layer warning when scissor rect is zero-sized. (#3472, #3462) [@StoneWolf]
 - Examples: Vulkan: Reworked buffer resize handling, fix for Linux/X11. (#3390, #2626) [@RoryO]
 - Examples: Vulkan: Switch validation layer to use "VK_LAYER_KHRONOS_validation" instead of
   "VK_LAYER_LUNARG_standard_validation" which is deprecated (#3459) [@FunMiles]
