Hey Yves-Alexis, thank you for your response.

Could you report this directly upstream because while I think it might be worth double-checking for division by zero, there's something fishy here (maybe with GDK as you said) and I think upstream would be better to check that.

Also not that in my case the monitor_width seems wrong (1920×1080 is the size of my laptop display but I'm currently docked to a 3840x2160 display which should be used for the calculation).
This seems to be intentional, the code selects the minimum screen width:
xfwm4-4.18.0/src/tabwin.c
344 static int
345 getMinMonitorWidth (ScreenInfo *screen_info)
346 {
347 int i, min_width, num_monitors = myScreenGetNumMonitors (screen_info);
348 for (min_width = i = 0; i < num_monitors; i++)
349 {
350 GdkRectangle monitor;
351 xfwm_get_monitor_geometry (screen_info->gscr, i, &monitor, FALSE);
352 if (min_width == 0 || monitor.width < min_width)
353 min_width = monitor.width;
354 }
355 return min_width;
356 }
xfwm4-4.18.0/src/tabwin.c
639 static void
640 computeTabwinData (ScreenInfo *screen_info, TabwinWidget *tabwin_widget)
641 {
[...]
655 tabwin->monitor_width = getMinMonitorWidth (screen_info);

Maybe it's something similar for you (in case you have a smaller display attached)?
Unfortunately, this is not my case. I don't have a smaller display. Ragards, Adam.
