Permanent Debug Output when using NavigationDrawer

Hi,

I had the problem in my application that when i do Navigation.PushAsync i get a white Page and the View is not loaded.
I tried to isolate the problem (took me a lot of hours...)
I found out that when i use a NavigationDrawer in a ContentPage i have a permanent output at the Debug Console:
04-06 17:38:55.532 D/Surface ( 6910): Surface::setBuffersDimensions(this=0x7fa0a2ee00,w=800,h=1280)
04-06 17:38:55.548 D/Surface ( 6910): Surface::setBuffersDimensions(this=0x7fa0a2ee00,w=800,h=1280)
I think the UI Thread is blocked and its not possible to display the View

I tried to make a project to reproduce it. I could reproduce the setBufferDimensions problem, but not the problem with the white page.

Attached is my sample project.

Thanks for testing.
Hmm, I think it depends on the device.
I had no problem running it on an Samsung Galaxy Tab S3 (fast device)
Also on the emulator everything runs correctly.
How do we have the possibility to correct the problem on this device?
