Internal self-test errors

Andreas Dumont
Posted 5 years ago

I keep running into internal self-test errors, e.g. if I use Free-form input and type "= caffeine molecule" and then click on the + to show all results. The scrollbar starts vibrating and the notebook is completely stuck. Sometimes it throws an internal self-test error with the file DXScreenGraphics.cpp. I'm running Mathematica 12.3 on Windows 10.

Thanks, Kerry, for the good info. The symptoms you described were exactly those I observed on two platforms (see my posts above).

My portal had ver. 12.3.1 for download. If my copy would work for you and it's permitted in the license, I can create a link to it for you.

Like you, tech support told me to run the CurrentValue function, which changed the option. The option you found successful to prefer GPU is not obvious to me in the options inspector. Can you suggest which of the following I should use: "Automatic," "Software," "Integrated," "Discrete," or "External"?

Since you still have 12.3.0 installed. It might be informative to see if eliminating any corruption in the preferenes file would solve the problem. That's what tech support said is usually the culprit. Because I installed 12.3.1 before resetting my preferences, I still don't know whether it was the version change or simply the full install of a new version that solved the problem in my case.

Jay & Others,

I did a clean restart by resetting Mathematica to its default conditions as per the instructions in this link:

http://support.wolfram.com/kb/12464

but to no avail. The problems persist. So I believe that Wolfram must have fixed a real bug in version 12.3.1 as per Jay's comments above.

I will wait for Wolfram Tech support to make version 12.3.1 available to me on my user portal (i.e. I will call them first thing on Monday morning EDT).

Regards.

The problem disappeared when I replaced ver. 12.3.0 with 12.3.1. What I would like to know is whether the version change corrected the problem or whether any full reinstall would have corrected it.

Wolfram tech support says most of the self-test errors are caused by corrupt preferences. During the three weeks I was back and forth with tech support, there was no awareness that a version change might be involved.

In my case, I had the same problem on two Windows-10 platforms. On the surface that might suggest that a preferences corruption was implausible. But both platforms were accessing the same notebooks. So as far as I know, it's possible a notebook error corrupted preference files on both computers in similar ways that caused the problem.

Thank you for the information. But how do I get Mathematica 12.3.1? I can't find it on the Wolfram website...

Check if the download is available in your User Portal

This seems to have been fixed in version 12.3.1

Thanks, Hans Milton.

I just saw your post today about ver. 12.3.1. I hope you're right.

The INTERNAL SELF-TEST DXScreenGraphics|ccp|174 and collateral Mathematica lock-ups have wrecked my workflow since early August. I saw your post today. It's the first reference I've seen to a solution or to a Mathematica update.

But how do I install the newer version? My user portal has a download link for 12.3.1. I can download it fine (2.038MB) It runs as expected. It finishes with a confirmation that the installation was successful. But Mathematica help>about still says 12.3.0. When the download executed, it returned the message saying installation was successful in about one second, which seemed a too fast.

I have not tried completely uninistalling Mathematica. Is that necessary?

Another puzzler: I've been back and forth with Wolfram tech support since 8/16/21. Last contact was yesterday, 8/31/21. Tech support acknowledged early on that the bug was known. It was blamed on an Intel GPU. But no one has said anything about a new version or a solution to the problem.

Jay, I upgraded from 12.3.0 to 12.3.1 in the beginning of July. Did not uninstall 12.3.0 before upgrading.

As I recall the "Express Download" was not available at that time, so I used the "Full Download". Both the download and the following installation took quite some time but went without any problems.

I am on Windows 10 as well and also have this problem on Mathematica 12.3 with Free-form Input / Show all results

Unlike you Andreas I don't get any Internal self-test errors. But as you say the front end becomes stuck. Cannot abort evaluation, close the notebook, start a new cell or do any other action. Only way out is to kill Mathematica through the Task Manager.

There is no problem on Mathematica 12.2
