PDF Viewer scrolls back to first page on every update

[fbbdev]

Pre-checks

• [x] The issue has not been reported in this repository.
• [x] 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

• Operating System: macOS Monterey 12.6.1
• Visual Studio Code Version: 1.75.1
• LaTeX Workshop Version: 9.7.0
• TeX Distribution Version: MacTex 2022

The Issue

• When I recompile my LuaLaTeX project with latexmk the PDF viewer is regularly updated, but it scrolls back to the first page. This makes it hard to check the effect of small updates, and in general makes the user experience much worse with long PDFs.

Reproduction Steps

1. Create a LuaLaTeX project with at least two or three pages worth of content
2. Compile the project with the command latexmk -pdflua -outdir=build toplevelFileName
3. Open the generated PDF in the internal viewer and scroll to the last page
4. Modify the source code and recompile with the same command as in step 2

At this point the PDF viewer updates and scrolls back to the first page.

Expected Behavior

• When updating, the PDF viewer should stay on the page that was visible before the update

[James-Yu]

Strange enough, there is no [Build] logs in your provided information, meaning that neither manual nor auto-builds were triggered. This makes it hard to identify the exact cause.

If you also observed repeated refreshes of viewer with a very short interval (several hundred milliseconds), you may try to increase the value of latex-workshop.latex.watch.pdf.delay. Increasing this value will make the extension less sensitive to file changes, which in turn triggers PDF viewer refresh.

[fbbdev]

There are no Build logs because I am building with a custom makefile. Increasing the watch delay solved the issue, thank you.
