Tibia Game Capture black screen - Streamlabs works, OBS fails to open shared texture handle

Hi everyone,

I have spent several days troubleshooting an issue with OBS Game Capture and Tibia.

OBS 31.x and 32.x both fail to capture the game.

The game remains black.

OBS log shows:

d3d11 shared texture capture successful

gs_texture_open_shared (D3D11): Failed to open shared 2D texture (80070057)

init_shtex_capture: failed to open shared handle

System:

• Windows 11 Pro 25H2
• Ryzen 5 5600
• AMD RX 580 2048SP
• Driver version 31.0.21925.1001
• OBS 32.1.2

Interesting findings:

• Streamlabs Desktop captures the exact same client.exe correctly using Game Capture.
• Discord can capture Tibia.
• Tibia internal screenshots work.
• OBS Game Capture, Window Capture (BitBlt and WGC) both fail.
• OBS issue opened here:
  https://github.com/obsproject/obs-studio/issues/13568

Has anyone encountered a similar issue or knows why OBS can hook the process but fails to open the shared D3D11 texture handle?

Thank you.
