Bug with Android styles in new version?
I have a program based on the Qt Widgets. It works fine on the all platforms with Qt 5.5. But I have a strange problem on Android with Qt 5.7 and Qt 5.8:
The program looks normal (all controls look native) at the first start. But all subsequent launches of the program does not look normal (the controls look like on a desktop).
I guess it's some bug in the Qt mechanism of styles caching. But everything worked perfectly in version 5.5. The value android.app.extract_android_style in the AndroidManifest.xml file is set to "full".
I set value android.app.extract_android_style to "none" for the test. And as a result, the program began to look incorrect already at the first start.
