Page break with minted: code gets out of background

Question

I'm using minted for displaying C++ code. If there is a long line at the bottom of the page, the line breaks as expected. Unfortunately there is also a gray arrow to indicate the line break.

How can I prevent this?

Edit: Here's a MWE to reproduce the problem:

\documentclass[a4paper,12pt]{report}
\usepackage{minted}
\usepackage{xcolor}
\definecolor{bg}{rgb}{0.95,0.95,0.95}
\setminted[c++]{breaklines,bgcolor=bg}
\begin{document}
\begin{minted}{c++}
#include <iostream>

int main() {
.

.

std::cout << "Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World" std::endl;
}
\end{minted}
\end{document}

The output looks like this:

minted package bgcolor scheme was not robust at page break. See manual page. 22.

Be aware that if bgcolor is used with breaklines=true, and a line break occurs just before a page break, then text may extend below the colored background in some instances. It is best to use a more advanced framing package in those cases

I recommend you use tcolorbox package which even provides a built-in framing environment with minted support. An example as follow:

\documentclass[a4paper,12pt]{report}
\begin{filecontents*}{test.h}
#include <iostream>

int main() {

std::cout << "Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World Hello World" std::endl;
}
\end{filecontents*}
%\usepackage{minted}
\usepackage{tcolorbox}
\tcbuselibrary{minted,breakable}
\usepackage{xcolor}
\definecolor{bg}{rgb}{0.95,0.95,0.95}
%\setminted[c++]{breaklines,bgcolor=bg}
\begin{document}
%\begin{minted}{c++}
\begin{tcblisting}{
colback=bg,
breakable,
listing only,
minted language=c++,
minted options={breaklines}}
#include <iostream>

int main() {

}
\end{tcblisting}
%\end{minted}
\tcbinputlisting{
colback=bg,
breakable,
listing only,
listing file={test.h},
minted language=c++,
minted options={breaklines}}
\end{document}
