React-native-navigation: [V4] Regression "Flash" on launch after Splash screen.

[jfrolich]

Issue Description

In 4.0.5 a regression is introduced that causes a noticeable flash of the background before showing the component (right after the splash screen disappears). I tried many different versions and it was introduced in 4.0.5 while still working in 4.0.4.

Steps to Reproduce / Code Snippets / Screenshots

See above

Environment

• React Native Navigation version: between 4.0.5
• React Native version: 0.61.5
• Platform(s) (iOS, Android, or both?): iOS
• Device info (Simulator/Device? OS version? Debug/Release?): Any

@jfrolich Are you using waitForRender when calling setRoot ? I assume the background image is an <Image> component set in JSX, right?

[jfrolich]

Yes I'm using waitForRender. There is indeed an image in the background (from the native asset catalog).

@yogevbd waitForRender seems to have broke in recent versions, any chance it's already fixed in v5?

[yogevbd]

Not sure, will check.

[guyca]

@jfrolich This should be fixed in v5, could you please update and let us know if the issue persists? Thanks.

[jfrolich]

Confirmed that 5.0 works.

[jfrolich]

BTW I had some issues making 5.0 work with Android. Would be good to put some documentation out when it is released.

[cspicuzza]

Is 5.0 stable enough for production?

[jfrolich]

Not sure, we shipped it though 🤫

[guyca]

@cspicuzza We're upgrading the Wix app to v5 next week. I'm not aware of any more issues.

@jfrolich Thanks for the feedback, We'll update the docs before release 👍

[jfrolich]

@guyca I didn't know about the docs in the issue related to the beta (I kind of had to debug my way into that solution), with that info it would have been smooth sailing.
