Window starts with a black screen

When the window starts up, I first see a black background and only then the drawn elements appears. Can this be avoided?

Happens in debug mode right? And it happens only once, correct? If not please provide more context for repro.

I tested the release environment and still have the problem. I used the TextEdit example, other examples should be the same. You can take a look at the screenshot.

I think Windows takes time to initialize some things at startup, probably in a different thread. Maybe you can try delaying the showing of the window until the app stabilizes.

These are just assumptions. In any case, this issue needs further investigation.
