But after upgrading to OBS 31, the OpenGL window capture is hanging.

Research direction
Start by reproducing the hang with OBS Studio 32.0.2 on Windows 10 using the OpenGL window-capture steps in the issue, then inspect the linked OBS log for relevant capture activity. Done means focusing the captured OpenGL window no longer causes window capture to hang, while older behavior remains unaffected.
