Hello,
I know that you are currently working hard on 4.13, but I would like to send you this warning may be this could helps if you can reproduce the issue by your side…
I’ve build a blank project for test. Building for Android was successful (with UE 4.13 (GitHub 4.13 branch)) : when I launch the app, the splash screen correctly appear but the default map doesn’t render correctly (see the first image bellow)
when the App lose the focus and re-gain it, then the scene appear well rendered… (very strange) I’ve searched in the UE source but have found nothing… may be the window initialisation ?
my device : Samsung Galaxy S5 SM-G900F (no rendering problem with 4.12.5 binary version with the same machine config)
Thanks for your support
Best Regards
Stéphane
