Hello, I'm working on making compiz use XI2 to get more fine-grain hold on keypresses. I'm however getting an issue: I do not always get NotifyGrab FocusIn events from the root window when a client calls
XGrabKeyboard (mydisplay, mywindow, True, GrabModeAsync, GrabModeAsync, CurrentTime); , which prevents from properly respecting grabbing. Unfortunately, I didn't manage to reproduce the issue with a simpler X root event listener: runnning XSelectInput(mydisplay, DefaultRootWindow(mydisplay), FocusChangeMask); does properly bring focus out/in NotifyGrab events, but these events don't get to Compiz. I also tried to listen on the window itself with the same result: my simple event listener gets the event, but Compiz does not. Oddly enough, this seems to depend on the application: kvm / virtualbox grabbing have the issue, but vncviewer grabbing doesn't have the issue. Reading https://tronche.com/gui/x/xlib/input/XGrabKeyboard.html tells me that there should always be FocusIn / FocusOut events being generated, so I don't immediately see where to look for in the differences between by simple listener and Compiz. Could there be some undocumented cases where such events are not generated? Any idea where I could look in the X server to check what is happening?
