Synfig Crashes when using Color Picker

Synfig 1.4.2 testing packages have been notified a moment ago over here Release version 1.4.2 ¡ Issue #2148 ¡ synfig/synfig ¡ GitHub

Here’s the link for Windows 64-bit installer: https://coolbug.org/downloads/morevna/builds/SynfigStudio-1.4.2-testing-2021.07.13-win64-1141b.exe

Can you check if this issue is reproducible for 1.4.2?

I still can’t reproduce it in 1.4.1 portable.

(and then I opened again when I saw I didn’t show the About dialog: )

So that is super strange. Where did you download Synfig from?

I downloaded syfnig from fosshub.com

It still crashes upon using the color picker tool.

Like @rodolforg I can’t reproduce Synfig crashing on WINE too.

@huddybuddy321 Can you do the following:

  1. Browse to Synfig Studio’s bin directory
  2. Launch Command Prompt (it’ll be in File menu)
  3. Execute .\synfigstudio.exe
  4. Use the color picker normally until it crashes
  5. (Synfig crashed) Capture the command prompt output and upload here.

The final output might be informative (…or might not)

I just tried it here and it works fine :confused:

Sadly, on Windows, GUI apps does not have any stdout/stdin/cerr/cout/cin/cerr.
He should edit the .bat launch file in Notepad to launch with --console. He could do it by changing this line:
start “” “%~dp0\bin\synfigstudio.exe”
to
start “” “%~dp0\bin\synfigstudio.exe” --console

<could be>
Also It could be an issue of capricious graphic driver, depending the format of pixel in memory where hovered.
Try to change settings like bits per pixels (16,24,32…) and change graphic acceleration of GFX card.
If possible upgrade your driver :stuck_out_tongue:

I can reproduce the crash. Unfortunately, when I open a cmd, go to the studio directory, and enter “synfigstudio.exe --console”, then when the crash comes, the console window crashes together with the program so I don’t have a chance to read what it says.

On a pure hunch: Synfig used to be quite stable under Windows for a long time. Then suddenly, around version 1.2, lots of versions appeared that crashed all the time for the feeblest reasons, even for just pulling down a guideline. Version followed version but the Windows problem never improved. In all the cases, Synfig didn’t manage to write any “death message”, and it never had any autosave to show either.

If I remember correctly, it turned out at long last that the transition from gtk2 to gtk3 was responsible for the trouble. The Windows version of the new kit kept throwing unexpected exceptions from the bowels of its code; these exceptions weren’t handled within Synfig and made the whole program crash.

Then someone issued a huge monster change where he diligently and laboriously encapsuled each and every d*mn gtk3 call with a try clause, and Synfig returned to normal under Windows again. (This is more or less hearsay; I don’t know the details; I’m not part of the programming team.)

The current symptoms remind me very much of that flaky Windows situation.

Soooo, might it remoootely be possible that some code flow is still left somewhere that calls the colour picker and has not been protected by a try?

@huddybuddy321 @PeterGB do you use dual monitor setup? I read on Google search some people complaining on this case.

Yes, I use dual monitor. I’ll update you on if unplugging my second monitor fixes the issue.

I uploaded my draft for a new Color Editor I mentioned on another post.
Could you try it and see if it crashes too? Here is my work-in-progress: WIP [Synfig Studio] new color editor by rodolforg ¡ Pull Request #2095 ¡ synfig/synfig ¡ GitHub . Windows users can test by following these steps. PS: As I just uploaded the code, you may have to wait some minutes.

Hello again. Any news?

Sorry, I took a break. I can confirm, unplugging my second monitor does fix the issue.

I have the same issue with Synfig crashing immediately upon using the color picker, moving to a color I want, then clicking on the color. It always crashes Synfig.
Link to video of issue

  • Synfig 1.5.1 (installed and uninstalled twice with reboot in between)
  • Windows 10 (updated)
  • Nvidia GeForce RTX 2060 Super (updated)
  • Dual monitor (same models, same settings for both)

I need both monitors so hopefully there is a solution for this. Thanks so much for any assistance.

But it works fine with a single monitor? Just for checking the cause of the issue

Thank you for responding so quickly. Disconnecting the 2nd monitor fixes the issue and it no longer crashes with the color picker.
Hopefully someone can find a way to make it work when both monitors are being used.

I have a dual monitor and turned one off, which fixed the color picker crashes. However, it continues to crash (except for the color picker) so I used your method and got the following errors (before it crashed).
See screenshot…

I navigated to the to the folder on freedesktop.org but do not know what to do with these files. I am running Synfig 1.5.1 64bit on Windows 10 (updated).

Sadly it doesn’t say what happened. It isn’t the issue that crashes Synfig.

Thanks for taking a look.

I have the same issue in Debian 12. Dual monitor. Dual CPU/GPU Nvidia + Cuda Nvidia drivers. Synfig 1.5.
But in my case, I don’t think it’s related to Synfig. I have crashes in other apps requiring high graphical ressources since last kernel update too, So I think it’s a Nvidia drivers issue not up-to-date to kernel in my case.
But I can relate that the crash happens with color picker too.
