Hi,
After update from 5.9.2 to 5.9.4 for Linux build, I found an issue.
Note: I use official precompiled release binaries.
After deploying my application showed weird artifacts in HTML content shown with QWebEngineView.
After some investigation, I found only this:
It qt.conf after deploying qt libs has Prefix with relative path Qt WebEngine renders HTML incorrectly.
I even tried to copy all qt libs and dependencies to make sure there is no missed libs or plugins - didn't help.
I've attached test project 'browser-test' that illustrate the issue with absolute minimum amount of code:
#include <QApplication>
#include <QWebEngineView>
QUrl commandLineUrlArgument()
{
const QStringList args = QCoreApplication::arguments();
for (const QString &arg : args.mid(1)) {
if (!arg.startsWith(QLatin1Char('-')))
return QUrl::fromUserInput(arg);
}
return QUrl(QStringLiteral("https://accounts.autodesk.com"));
}
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QApplication app(argc, argv);
QWebEngineView view;
view.setUrl(commandLineUrlArgument());
view.resize(1024, 750);
view.show();
return app.exec();
}
test.html:

<html>
<head>
<meta charset="UTF-8">

Check attached screenshots for actual results of running:
./browser-test $(pwd)/test.html
with relative Prefix path in qt.conf - incorrect-html-rendering.png
with absolute Prefix path in qt.conf - correct-html-rendering.png
Windows and MacOS builds are working fine.
