This has been noticed with UE4: https://answers.unrealengine.com/questions/255771/strange-window-behavior.html

When raising window, the following message is printed (in Gnome):

Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x3a00046

This is because X11_XRaiseWindow is using CurrentTime as a timestamp when sending _NET_ACTIVE_WINDOW. According to the spec (http://standards.freedesktop.org/wm-spec/1.3/ar01s03.html):

"The timestamp is Client's last user activity timestamp (see _NET_WM_USER_TIME) at the time of the request"

(was too quick to send the previous comment): ... according to the spec, this should match _NET_WM_USER_TIME (which SDL never sets either).
