Hello,

I have a brand new install on Fedora, using the beginner install script ([https://github.com/node-red/linux-installers](https://github.com/node-red/linux-installers)) and none of the dropdown menus are viewable. I can 'select' them and use the arrow keys to sort-of tab through the hidden options, but a dropdown menu showing the complete contents does not work.

System:  
Fedora 31  
Firefox 70.0.1  
NR: 1.0.3

Steps to reproduce:  
Install on fresh F31 image, using script from rpm installers repo  
open localhost:1880  
attempt to use dropdown for 'repeat' in Inject node.

Interestingly, dropdowns for 'payload' work fine (and others with grey background).

Hi @dcsouthwick

That is very odd - the `repeat` element in the Inject node is a completely standard HTML `<select>` element with _no_ custom code running against it (unlike the payload drop-downs which are custom elements).

Are there any error messages in the browser console?

Another bit of info I found for devs while trying to make a screencast of this problem.  
It seems triggered when there is more than one monitor.  
Doublescreen webcast (scroll right for 2nd screen and demo of broken dropdowns)  
[https://webm.red/EIKi](https://webm.red/EIKi)  
same actions, with one monitor disabled:  
[https://webm.red/w0p4](https://webm.red/w0p4)

This actually seems to be some sort of bug

I'd suggest a bug with Firefox then - the rendering and interaction of those elements is provided by the browser and nothing to do with the node-red editor code.

Can you try a different browser to see if that's the case?

Yes, just installed chromium, and html renders as expected. Weird.
