Howdy,
During testing of my IPC patch, I've found an edge case that might be
worthwhile to investigate.
If a window currently has the focus and the mouse is placed within the
window bounds, moving the mouse over (not beyond) the window border
triggers a focus change although the window is already focused!
As I don't know whether this behavior is intentional, I've addressed
this use case specifically for my code path in con.c->con_focus() to
avoid sending pointless window events. Might be possible to extend the
checking to the whole method to spare some cycles.
Cheers,
Marco
