PDF viewer turns blank after refreshing when spreading is enabled #4415

Closed LinqLover closed 1 month ago

LinqLover commented 1 month ago

Pre-checks*

Please change the following [ ] to [x] for confirmation.

  • [ ] The issue has not been reported in this repository. No, it has been mentioned: #4300 (closed as not reproducible) and https://github.com/James-Yu/LaTeX-Workshop/pull/4295#issuecomment-2188891983 (issue there was apparently fixed)
  • [ ] The issue remains after disabling all other extensions and restarting Visual Studio Code.
  • [x] The FAQ cannot address the issue.
  • [x] The issue is not related to compiling a document, or the document can be successfully compiled in the OS terminal but not in Visual Studio Code with this extension.

Environment*

Please write exact version numbers instead of descriptors such as latest.

  • Operating System: Linux x64 6.5.0-45-generic (Ubuntu 22)
  • Visual Studio Code Version: 1.93.1
  • LaTeX Workshop Version: v10.4.1
  • TeX Distribution Version: TeX Live 2022

The Issue*

Please briefly describe the issue you come across.

  • PDF viewer (in browser or in VS Code tab) becomes blank after refreshing document when spreading (Odd Spreads/Even Spreads) is enabled

Reproduction Steps

Please list out the steps to reproduce your bug. Include relevant environmental variables or any other configuration.

  1. MWE: 
    % !TeX root = test.tex
\documentclass[twoside]{scrbook}
\usepackage{blindtext}
\begin{document}
\Blinddocument
\end{document}
  2. Save
  3. Command latex-workshop.view or latex-workshop.viewInBrowser
  4. In the menu at the right top corner, select "Odd Spreads" or "Even Spreads"
  5. Command latex-workshop.refresh-viewer
  6. Do some scrolling in the PDF viewer
  7. Now, the viewer "crashes": it turns blanks and the scroll bar is lost. F5 in the browser helps but then the viewer state (scroll position, view mode, etc.) is lost. See errors below.

Expected Behavior

What were you expecting to see? Include any relevant examples or documentation links.

  • The file should just be updated

Here is another observation that is possibly linked to or caused by the above, so I will post it here, but of course it can still be moved into a different issue:

% !TeX root = test.tex
\documentclass{scrbook}
\usepackage{blindtext}
\usepackage{pdflscape}
\begin{document}

\blindtext
\clearpage
\blindtext
\clearpage
\blindtext
\clearpage
\blindtext
\clearpage
%\begin{landscape}
\blindtext
%\end{landscape}
\clearpage

\end{document}
  1. Build this, open in viewer, turn on Even Spreads (as above)
  2. Uncomment the landscape environment-related lines and save to rebuild
  3. PDF in viewer turns blank (as above)
  4. Use the menu to switch to a Odd Spreads or any other option
  5. Now, the PDF can be read again, but the final page is incorrectly displayed as a portrait page (with text that overlaps its bounds) until you refresh the page. When zooming out, I can also very briefly see a distorted version of the text.

This seems to be caused by a strange reason which persists even when the viewer is not in spread mode. I observed this problem when there are multiple pdfs opened and the one being refreshed is not currently in view. To reproduce, compile the tex file (with the pdf hidden) several times with minor changes. Then after clicking on the pdf tab for that file again, one will observe this problem.

It seems that VS Code (or Chrome in general) does some optimization by not letting JS run fully when a tab is not visible. So, the PDF reloading sequence is messed up, and our code injection to delete pages, etc., does not work correctly. When this happens, the new pages are appended, but the old ones aren't deleted.

Meanwhile @tamuratak implemented a very elegant way to remove flicker using a mask with the old content copied and then remove the mask once the page has been loaded. It is much less invasive than what we have now. https://github.com/tamuratak/latex-toybox?tab=readme-ov-file#true-flicker-free-reloading @tamuratak Can we adapt your code? @James-Yu What do you think about replacing what we have with this new implementation?

James-Yu commented 1 month ago

I am fine with adapting to the new logic as long as license permits. However, I am not working on the viewing part. Would you kindly take the role? @quoc-ho

quoc-ho commented 1 month ago

@James-Yu Great! I'm happy to look into it, but most likely in the winter, after the semester is over. I'm a bit swamped at the moment.

James-Yu commented 1 month ago

That would be awesome! I’ll check the code shortly and see if it is a large work or not.

quoc-ho commented 1 month ago

@James-Yu I took a look a while ago, and it seems that it's actually less than what we had to do in our implementation.

LinqLover commented 1 month ago

Great, thank you for all the swift fixes! Can I ask when these changes are usually live in the VS Code Marketplace? :)
