Comment 23 for bug 1849478

Robie: I just tested on jammy, and I'm seeing something different: with the flag enabled, screen sharing works (although I do get the window selection pop-up displayed twice, same as on impish). Without the flag, I'm seeing a black screen with the mouse cursor, like you do.

Could you test again with the latest chromium from the stable channel, on an up-to-date jammy, and let me know if your observations are consistent with mine?
