Odd issue - text shows up only when scrolled around

Hi folks, I am stumped by a problem reported by a few Android users (doesn’t happen on desktop or iOS). Any ideas where I can look? The users say this problem started a few versions ago of my app - that is when I updated ionic.

The problem is that text on lists don’t show up till they scroll. These are standard ion-content lists (source code) (I tried removing scroll-vista and mouse-wheel directives - no effect). This is just one view - the problem is consistent for any ion-content that scrolls.

Ionic info

Your system information:

Cordova CLI: 6.5.0 
Ionic Framework Version: 2.0.0-rc.1
Ionic CLI Version: 2.1.17
Ionic App Lib Version: 2.1.7
ios-deploy version: 1.9.0 
ios-sim version: 5.0.2 
OS: macOS Sierra
Node Version: v5.11.0
Xcode version: Xcode 8.3.1 Build version 8E1000a


Does it happen for all Android users?
Is it on specific devices or OS versions?

So far Android 7.1.2 and a Nexus tablet running Android 6. I tried running it on an emulator with 7.1.2, I don’t see the problem. So at this stage, I don’t know if its a device specific issue.
