OBS 28.1.2, installed via PPA
Ubuntu Studio 22.04.1 LTS
Window Capture (Xcomposite) appears to try - it has a correct list of all the window titles - but it still doesn't actually show anything for any of them. See screenshot.
Window Capture (PipeWire) doesn't even have that. Its Properties window shows blank, and a Select button. Clicking that button does nothing.
Screen Capture (XSHM) works completely. But I want a window that is usually behind others.
Screen Capture (PipeWire) does the same as its Window counterpart. Properties is blank, and Select does nothing.
Logfile:
Terminal, with the command taken from a script that sets up a more complex rig than just this:
