Map flashes black when opened from another activity

[genericusername3]

Mapbox SDK version: com.mapbox.mapboxsdk:mapbox-android-sdk:9.1.0

Steps to trigger behavior

1. Use a real device, not an emulator, because emulators don't have the issue for some reason
2. Open an activity with a map using an Intent
3. Perform usual steps (set token, add style etc.)

Expected behavior

Map renders correctly

Actual behavior

Map flashes correctly rendered, then turns black with attribution still visible for more than a second and finally appears correctly rendered again.

I've tested this on multiple devices and emulators and this bug seems to affect devices prior to Android 10.

Note: 2020-04-27 18:01:00.124 12598-12598/de.kaffeepott.mockup D/ViewRootImpl[MapActivity]: changeCanvasOpacity: opaque=false happens at the same time as the map showing correctly again and I would guess canvasOpacity has something to do with this.

Overall, my issue sounds exactly like fixing this issue should have fixed it, but it still persists

@genericusername3 Thanks for reporting this. Can you upload your test project or create a new project that could reproduce this issue to GitHub and share it with me?

Hello,
I want to report the same problem, but without the flashes;
my map is always rendered black, with only the mapbox logo visibile.
This happen either in emulator and real device.
I've tried to fix in many ways, like changing ndk version, changing emulator render engine, and other, but problem still persists.
I've noticed in the debug log, mapbox call tiles, symbols and icons of the map correctly, but unfortunately they are not showed on screen.
This is content of my build.gradle module file:

android {
    compileSdkVersion 28
    ndkVersion "21.1.6352462"
    buildToolsVersion "29.0.2"

    defaultConfig {
        applicationId "com.vintesmobile"
        minSdkVersion 28
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.core:core-ktx:1.2.0'
    implementation 'com.google.android.material:material:1.1.0'
    implementation 'androidx.annotation:annotation:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'com.squareup.okhttp3:okhttp:4.6.0'
    implementation 'org.conscrypt:conscrypt-android:2.2.1'
    implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:9.2.0'
}

Thank you in advance.
Let me know if you need further help.
