Full screen while screen recording: the pointer disappears, buttons aren't responsive
Start recording the whole screen using the shell's built-in tool, then full screen Loupe. The pointer is no longer visible. In some cases I've been able to click the full screen button, but the window hasn't exited full screen. I can still use F11 to exit full screen.
I've reproduced this issue while testing with an installed Flatpak and with a local JHBuild build.
