Hello, there is a problem with DWM when using LWA_ALPHA, this flag will decrease the performance a lot. In my case it uses 20-30% GPU and that's a lot.
I also have my own project based on directx11 for an external overlay and after I optimized most of my program I realized there are low usage % but still unstable fps and sent me to this process that's eating my GPU after running the overlay.
I couldn't find a fix for this but people suggested making the back buffer transparent since your window is already transparent from the flag WS_EX_TRANSPARENT in CreateWindowExW.
I saw your other repository called Imgui-Standalone and after a quick run it doesn't affect DWM's performance that much, a choppy fix would be to create the window as fullscreen and just limit the "ImGui::Begin" to targeted client's window dimensions. I didn't have the time to go through your both project's code, I just realized you got the same method for making the window transparent as me. I am sorry for this, I will go through it in-depth tomorrow and come with edits/news if any.

While building the project im keep getting this error.

Hello, I'd like to know how to make sure that when I press the insert key my mouse can move freely because on fps games I can only move my mouse by clicking on the right click because the game blocks the mouse in the middle of the screen and I'd like to know if it's possible to block that the game can control the mouse (sorry if I expressed myself badly).

it does not draw the full screenHeight .
it does not draw the bottom part in the MSTaskListWClass

I had these problems when compiling. I have DXSDK_DIR declared in environment variables and the latest version of DirectX installed. I also set the path to DirectX in Properties in VC++ Directories in Include Directories
