Full screen projector seems to be broken with multiple displays

My system has 5 display monitors. Two are connected to the first graphics card, two to the second graphics card and one to the USB to HDMI adapter.
Was using OBS 26.0.2. Full screen projector worked just fine.
Upgraded to OBS 27.1.3. Now full screen projector always projects to the first display no matter which display is selected as the target display.

Now installed both OBS 26.0.2 and OBS 27.1.3 in portable mode (in separate directories). With OBS 26.0.2 full screen projector works just fine (i.e. projects to the selected display). With OBS 27.1.3 full screen projector always projects to the first display no matter which display is selected as the target display.
