Can you take a look into this (only for lualatex engine) ```latex \documentclass{article} \usepackage{pgf,tikz} \usepackage[showframe]{geometry} \parindent0pt \makeatletter \newif\ifpgf@rldir \pgf@rldirfalse \def\pgfrldirtrue{\pgf@rldirtrue} \def\pgfrldirfalse{\pgf@rldirfalse} \newdimen\pgf@rlpicminx \newdimen\pgf@rlpicmaxx \def\pgfpicture{% \begingroup% \pgfpicturetrue% \global\advance\pgf@picture@serial@count by1\relax% \edef\pgfpictureid{pgfid\the\pgf@picture@serial@count}% \let\pgf@nodecallback=\pgfutil@gobble%...

**Example** ```latex \documentclass{article} \usepackage[showframe]{geometry} \usepackage{pgfpages} \def\pgfpagespoint#1#2{\pgfpoint{-#1}{#2}} \pgfpagesuselayout{4 on 1}[a4paper,landscape] \begin{document} \pagedir TRT \bodydir TRT \pardir TRT \Huge Page 1 \newpage Page 2 \newpage Page 3 \newpage Page 4 \end{document} ```

Changes are for monolingual documents (latin or arabic), for others cases I don't know how it will be done. Please add what you see suitable.

Thanks, for #910 I thought the feature is useful for xelatex with `bidi` package if one need pages to be placed from right to left.

Hi @hmenke , perhaps it would be better to change `\pgfpoint` with another command `\pgfpagespoint` in pgfpages.sty with the same definition by default in case of TLT page, and with...

@FrankMittelbach Thanks for the guidance, the confusing thing is why the issue appears only with `align*` environment and It does not appear in similar environments as mentioned by @muzimuzhi !

Can you show me guidlines to obtain style for right to left presentations based on beamer ( perhaps creating new class "rl-beamer" with modification on beamer sty files )

@josephwright take a look to https://github.com/seloumi/rl-beamer In your opinion creat new class from beamer only for right to left presentations or improving changes (not yet complete) and add "rtl" option...

With double vrule the defect becomes greater ```latex \documentclass{article} \usepackage{tabularray} \textdir TRT \begin{document} \begin{tblr}{|c||} \hline one \\ \hline \end{tblr} \end{document} ```
