That does not happen to me. My xterm seems to ignore the fact that 'd'
is held down until Ctrl is released, at which point it starts producing
However it does not matter.
The important point is that in both your and my case the client that has
just received focus sees the 'd' as being held down. The 'd' is on in
the key-down array attached to the focus-in event!!!!
Apparently if Ctrl+D was a "compositor shortcut" to close a window, then
this patch will cause the 'd' to not be there. But since Ctrl+D is
handled by a client to close the window, the client with the new focus
*does* see it. WHY IS THIS DIFFERENT??????
IMHO they should not be different, therefore this patch is wrong. There
are two possible solutions:
1. Revert it. The actual bug is that a client that already has focus
before a "compositor shortcut" will not get any changes to the keymap.
Add something to fix this instead. I recommend a redundant focus-in event.
2. Always send a blank key-down array in the focus-in event, since it is
possible that any key held down was the "shortcut" that caused the
