I have just noticed very strange behavior.
I have a blueprint based HUD which uses the Draw Text node to display various information about the current level. The text is correctly rendered on PC, Mac, iOS (both iPad and iPhone) and a Nexsus 5. But when testing it on Nexsus 7 (2012 model) the text is not rendered at all. I have tested this on 2 different Nexsus 7 devices, both running Android 4.4 (Nexsus 5 is also running 4.4). I will attempt to get other devices to test with to see if any other device suffers from the same issue.
