|With Ubuntu 17.04/Metacity there are warning messages written to console, like: |
Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x4a00003 (win1)
Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
Noticed with the test programs 'twowin' (when clicking on buttons b1/b2) and 'windowfocus' (when entering text).
These come from Fl_x.cxx line 2228, where 0 is used as timestamp.
I tried using fl_event_time instead, which seems to work.

|Can still be observed with Ubuntu 17.10 when running with Gnome-Session-Flashback/Metacity (XDG_SESSION_DESKTOP="gnome-flashback-metacity"). |
It occurs only, when Metacity is configured to run non-compositing (this can be achieved with: metacity --replace --no-composite &).
