Ionic v4 render problems in Chrome OS

I’m creating a cross-platform application to run on both iOS and Android, and I’ve been testing it on a Chrome OS device as well by running the Android app in Chrome OS.

When I run the device on my Android tablet, it works perfectly, but when I run the same Android application on the Chromebook, there are a ton of rendering issues - large white spaces where elements should be displayed, no text rendering until I mouse over it (and even then only about half the letters appear). This was all working for me until about a month ago, so I’m not sure what happened. Chrome OS should be rendering the app exactly the same as Android does.

Anyone else have this issue? Any ideas for how to fix it?
