New ionic 5 app doesn't render correctly in browser

I have a problem accessing the sidemenu ionic app in browser. The screenshots below are of a new created ionic app with sidemenu.

In full screen mode:

If the browser is a fraction of the screen size:

As you can see here the menu icon is shown as it’s supposed to be and I can access the sidemenu.
The only thing I added here for demonstration purposes is the fab button with an icon. But as you can see the icon inside the fab button is not show. In my other - recently created real ionic project, things like the back button don’t render correctly.

As a side note however, sometimes everything renders correctly. This is like 1 out of 50 times the app reloads when am going about my business. So majority of the time it’s as shown about then once in a blue moon everything works.

I am developing a PWA so access to the sidemenu is very important.

I need some some help.
