Vulkan renderer breaks Alt1 DX/OGL capture

Since RuneScape added the Vulkan renderer option, Alt1's DirectX/OpenGL capture no longer works when Vulkan is selected, so it reverts to desktop capture.

The problem: desktop capture grabs the composited desktop output, which includes Alt1's own overlay. That creates a feedback loop - any overlay drawn on top of the game (dots, highlight boxes, text) ends up baked into the captured frame.

This breaks pixel/colour-based detection for any plugin, because a plugin's own overlay corrupts the very capture it's reading from.

  Steps to reproduce:

  1. In RS graphics settings, switch the renderer to Vulkan.
  2. Alt1 wont show any image for rs2client.exe linked window with DirectX or OpenGL Capture selected

DirectX only works for certain hardware configurations, I'm curious to see if the people that used DirectX for capture can still use it with Vulkan. So even under the OGL version, you probably wouldn't be able to use DirectX.

I used DirectX Capture as a capture for OGL Renderer. It still works when I switch to OGL Renderer.
When switching to Vulkan Renderer , nor DX or OGL Capture function correctly.
