Here is simple test code.
\documentclass{beamer}
\begin{document}
\begin{frame}
a
\end{frame}
\begin{frame} b bb bbb bbbb bbbbb \end{frame}
\end{document}
When I use "go to pdf" (or ctrl+click) below the "bbb" line, it goes to the second frame.
However, when I use it on "bb" or "b" line, it goes to the first frame, which should be the second frame.
This error is very annoying for me.
Do I something wrong? My file name doesn't have any blank, dot or special letter.
With TeXstudio 2.12.16 and TeXlive 2018 they all go to the second frame
