Geometry margin causing tasks alignment issue

Question

For some reason, if one sets a margin using the geometry package, this causes an alignment problem with the tasks package:

MWE:

\documentclass[12pt]{article}

\usepackage{amsmath,geometry,tasks}
\geometry{a4paper, margin=2cm}
\NewTasks[counter-format={tsk[a])}]{problems}[\item](4)

\begin{document}\raggedright

\begin{enumerate}
    \item Prove the following:
    \begin{problems}(4)
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \end{problems}
    \end{enumerate}

\end{document}

Interestingly, at certain values, e.g. margin = 1in, there is no problem. But at other values, such as margin = 0.5cm, which is smaller than a 1in margin, there are problems. This eliminates a minimum width issue. What is the solution to this?

\raggedright does some magic internally, and is being responsible for the issue you see. — Johannes_B, Sep 17 '17 at 06:42

One should reset \@rightskip. Imho the tasks package should do it. So make a bug report:

\documentclass[12pt]{article}

\usepackage{amsmath,geometry}
\usepackage{tasks}


\geometry{a4paper, margin=2cm}
\NewTasks[counter-format={tsk[a])}]{problems}[\item](4)

\begin{document}\raggedright

\begin{enumerate}
    \item Prove the following:
    \begingroup
    \makeatletter 
    \@rightskip=0pt
    \begin{problems}(4)
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \item $x$
        \end{problems}
      \endgroup         
    \end{enumerate}

\end{document}

You could use \AtBeginEnvironment{problems}{\setlength\@rightskip{0pt}} (requires etoolbox). – egreg Sep 22 '17 at 09:41
I added something to my tracker so I don't forget: https://github.com/cgnieder/tasks/issues/10 – cgnieder Sep 22 '17 at 13:14
Would there be any way to wrap this in an environment? E.g. (with xParse) \NewDocumentEnvironment{dummyEnvironment}{} {\begingroup \makeatletter @rightskip=0pt \problems(2)} {\endgroup\endproblems} Doesn't work. – Harry Sep 25 '17 at 05:55

Could a solution with \RaggedRight from ragged2e package be acceptable?

EDIT: Ulrike has already given the perfect answer but I'd like to add TeXnician's suggestion (\usepackage[none]{hyphenat}) to my original answer:

\documentclass[12pt]{article}

\usepackage[none]{hyphenat}

\usepackage{amsmath,geometry,tasks}
\geometry{a4paper, margin=2cm}
\NewTasks[counter-format={tsk[a])}]{problems}[\item](4)
\usepackage{ragged2e}

\usepackage{mwe}

\begin{document}\RaggedRight
    \blindtext
    \begin{enumerate}
        \item \blindtext Prove the following:
        \begin{problems}(4)
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
        \end{problems}
    \end{enumerate}
    \blindtext
\end{document}

Moreover, as egreg suggested to me in chat, another simple solution could be justifying only the problems environment:

\documentclass[12pt]{article}

\usepackage{amsmath,geometry,tasks}
\geometry{a4paper, margin=2cm}
\NewTasks[counter-format={tsk[a])}]{problems}[\item](4)
\usepackage{ragged2e}

\usepackage{mwe}

\begin{document}\raggedright
    \blindtext
    \begin{enumerate}
        \item \blindtext Prove the following:
        \begin{justify}
        \begin{problems}(4)
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
            \item $x$
        \end{problems}
        \end{justify}
    \end{enumerate}
    \blindtext
\end{document}

The output is more or less the same as before:

Problem is the hyphenation that occurs with that. If there is a way around that, we might have a solution! — Harry, Sep 22 '17 at 08:11
Hi! Please leave it up, someone else might know how to fix the hyphenation problem. — Harry, Sep 22 '17 at 08:16
For hyphenation https://tex.stackexchange.com/questions/5036/how-to-prevent-latex-from-hyphenating-the-entire-document could help. — TeXnician, Sep 22 '17 at 08:56
