Hey @Steve018
Thanks for the reported issue!

I am getting this on LG G5 (Android 7.0) - 1440 x 2560 pixels (~554 ppi pixel density) and Nightly 63:

However, the menus take like 3 seconds to open, once they are tapped.
Let's diagnose this. Maybe @wisniewskit can help.

Well now...
I see Google Pixel (Android 8.1.0) - 1080 x 1920 pixels (~441 ppi pixel density) is more special:

In RDM, only the sluggish menu is reproducible.

@softvision-sergiulogigan
I see now that each menu item is loading extremely slow (~10s after tap). I misunderstood it as the menu not working.

This is loading but it is slow indeed. And it is almost immediate in Chrome.

I created a profile where I opened a submenu and then closing it. Twice. https://perfht.ml/2OhzL5V

We can see in the performance profile. the two black bars.

The perf profile says that it is 804ms doing something and point to utag.loader.loadrules in https://tags.tiqcdn.com/utag/samsung/main/prod/utag.js

yes there are a lot of case with a similar construct.

        case '15':
          try {
            c[15] |= (typeof d['order_ID'] != 'undefined' && d['dom.referrer'].toString().indexOf('samsungpowerbot.com') > - 1) || (typeof d['order_ID'] != 'undefined' && d['dom.referrer'].toString().indexOf('trypowerbot.com') > - 1)
          } catch (e) {
            utag.DB(e)
          };
          break;

Probably something to open on bugzilla directly.
