Can you post a link to your test apk.
I have an older device with 5.1 on and can test to see if I see the same results.

Ok, tested on 5.1 Huawei Y6 and works ok, but very slow black screen startup.


Moved the acceleratedrenering to preOpenStack fro openStack which reduced black screen startup time, but its still 6 seconds.

Tested also on Nokia 6 android 8.1 all works ok... 2 second startup time.

So it looks like as you said its a problem with the particular meizu phone device.

Now with lC901rc2 i have this problem too, so it seems not fixed but reintroduced.
I turn on and off the accelerated on the cards i need to prevent the shifting of the screen. (was this solved already?)
Now before returning to a previous card i turned it on again and then the screen turned black.

So i could decrease the black screen by first turning on the accelerated again, then wait for 50 milliseconds (i just tried some) and then go to the previous card.

Did not have the issue with previous versions of LC.

Thank you to give details about the Android devices you're using, and Android version.

This is on a cheap Wiko Jerry (what's in a name) Android 6. But it's not at start up, but when changing the cards after turning off and on the accelerated.

The problem with black screen at startup i had on an Samsung (don't know the model exactly) Android 7, but this was solved with the solution Panos gave in a bug report.
