Tex Studio crashes if moving around in a reasonably large (100 pages) PDF with embedded PDF graphs

[rtayloressex]

Hi. The latest update to tex studio has brought a new undesirable feature not present in the previous version. When you scroll in the PDF preview window faster than tex studio would seemingly like you get a little round blue circle then the whole system crashes. You then have to re-open tex studio and then re-open the file(s) you were editing. This has only happened since the update last month. It never happened before, including when working on the same files, in the previous version. It seems therefore that the update is unstable.

I can only reiterate what was asked when opening the issue

<!-- add as much describing information about your issue as necessary -->
<!-- remove empty sections -->
### Environment
This is important !!!!
- TeXstudio: <!-- VERSION 	-->

- OS: <!-- Windows(7,8,10), Mac, Linux (Distribution), ... -->
- TeX distribution: <!-- miktex, texlive, ... -->

### Expected behavior
okay

### Actual behavior
okay, pdf viweing crashes, that is fine.

### How to reproduce
Give an example, e.g. the pdf which crashes

Hi. Apologies.

It is

TeXstudio 4.8.5 (git 4.8.5)
Using Qt Version 6.8.1, compiled with Qt 6.8.1 R

Running on Windows 11

Using latest version of Miktex (no updates currently needed) running in Miktex console 4.12

the PDF involved is 100 pages with embedded PDF graphs. It's attached

CUSUMrevision2101MCedit.pdf

In case also useful ...

This is pdfTeX, Version 3.141592653-2.6-1.40.26 (MiKTeX 24.4) (preloaded format=pdflatex 2025.1.27)

not reproducable with the given document (and also not with my 1'008 pages pdf).

Win 10 pro on Intel
TeXstudio 4.8.6 (git 4.8.6beta1-4-gc4efbe39e)
Using Qt Version 6.8.1, compiled with Qt 6.8.1 R (I think this is 6.8.1-3)

Hi. Don't know what to say then, as it happens to me often, 5 times today already (but has only happened since I installed the last update of tex studio - never happened before that) when using the vertical scroll facility on the far right hand side of the PDF viewer. It also can happen if two latex files are open both with their PDFs open and I click back from the other to the big PDF I uploaded that is crashing - at that point the little blue circle keeps going round until the whole tex live process just crashes and closes.

In fact I can crash tex studio at will just by spinning this scroll facility up quickly on the big PDF ... it is basically very unstable.

Your tex studio version is not the same as I have been using. Is there another update?

[rtayloressex]

The tex studio system tells me it is up to date when I check.

[rtayloressex]

I might have to go back to tex works it seems :(

The texstudio version I used for the test is a local build of the source code (with msys2). You can test yourself builds generated automatically with each change in development. Select latest (at top) or one as you like and click the link. What was built can be seen to the left:

Scroll down to Artifacts:

Here you can download what you need for your system. The zip named at the end of the list is a portable version and needs no installation.

Thank you, but that is beyond my computing skills! I just want something off-the-shelf that runs reliably with the standard download. Tex Studio was exactly that until the last upgrade when this problem with it crashing started. It seems the latest upgrade is unstable. Shame as the version before the upgrade was brilliant. I hesitated to do the upgrade as it was working fine before. I wish I had not now.

[sunderme]

you can go back to any version.

[rtayloressex]

OK. Do you need to uninstall the latest release to install an older release, please?

[octaeder]

no, otherwise you may loose your settings.

[rtayloressex]

So just download and install older version of choice without uninstalling latest version? Thanks for your help. Much appreciated!

[octaeder]

I would do so

[rtayloressex]

Thanks. I installed 4.8.1 (which I think is the version I was running before the upgrade) in a different folder location from the latest version 4.8.6 and the problem has vanished when I run the older version but still happens with the new version. It does look like there must be something about the PDF viewer and the latest version that my windows 11 PC does not like ...

[octaeder]

Thank you for sharing this with us. If you like you could run 4.8.5 (4.8.6 is next release in the future) with a complete default configuration to see what happens then. To do so, you need to end txs, then rename the config folder. The folder's name is texstudio and should be found under %appdata% (windows explorer will replace this with the correct path). Then start 4.8.5 and make your testing. After all you should restore the original name of the config folder.

[rtayloressex]

Hi. Not sure I'm of sufficient computing skills to do that I'm afraid. The older version is working and if no one else is having the problem then maybe it is just my machine ...

[octaeder]

this is ok, thanks.
