Oh my goodness. I just found out the culprit was the Gnome extension "Multi Monitors Add-On". I had originally installed this extension so that I can have the top bar on both monitors. But after disabling it, right click menus works fine !
I'm going to file a bug report with the author of that extension. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1832449 Title: Right click menu does not appear near the mouse on multi-monitor setup Status in gnome-shell package in Ubuntu: Incomplete Bug description: I have an external monitor connected to a laptop via HDMI.
