Yes all these features are related to the layout, so it is "normal" they 
also fail.

Perhaps do you use the new MonitorLayout variable?

If not, could you share your config (at least in mp)? so I can try to 
reproduce the problem.

You can add some logs in RLayoutFullVert1 function in r_layout.c 
(backend for f.zoom):

RLayoutFullVert1(const RLayout *self, const RArea *area)
{
   fprintf(stderr, "RLayoutFullVert1, layout: ");
   RLayoutPrint(self);
   fprintf(stderr, "area: ");
   RAreaPrint(area);
	// Let RLayoutFull1() find the right monitor.
	RArea target = RLayoutFull1(self, area);
	int max_x, min_x2;
   fprintf(stderr, "target: ");
   RAreaPrint(&target);

Interesting.

Max.
