Bug 36601

This bug still persists on a freshly compiled spicec from current master (4e7d25a7ac). Please let me know how can I asist in getting to the bottom of this. Changing a WM is not a course I'd like to pursue.

Cheers

I'd recommend to switch to remote-viewer (from the virt-viewer package) as this is the client we support.

I second that recommendation. If you want to try to fix this, this seems to be the only place where we do a XSetInputFocus: (client/x11/red_window.cpp)

void RedWindow::activate()
{
    //todo: use _NET_ACTIVE_WINDOW
    XSetInputFocus(x_display, _win, RevertToParent, CurrentTime);
    /* kwin won't raise on focus */
    XRaiseWindow(x_display, _win);
}

Just hit same bug. Looks like it works ok when executed under strace. Maybe it just doing something "too fast"? :-/

From http://lxpanel.sourcearchive.com/documentation/0.5.5-1/taskbar_8c-source.html

      /* There is a race condition between the X server actually executing the XMapRaised and this code executing XSetInputFocus.
       * If the window is not viewable, the XSetInputFocus will fail with BadMatch. */

Actually, looks like commenting this line fix this issue. It's a VM window, we anyway many times enter/leave it, having to click before use isn't a big deal.

spicec is deprecated.

If you hit this bug, we highly recommended virt-viewer
