mate-screenshot dialog crashes

[spartanhooah]

Expected behaviour

I can take and save a screenshot when hitting the PrtSc key.

Actual behaviour

A "Save Screenshot" window opens with the screenshot, but there's an error dialog in front. It says "Unable to save the screenshot to disk:

Fatal error in PNG image file: Write Error"

If I click the OK button on the error dialog, both it and the "Save Screenshot" window close. If I alt-tab, then the error dialog goes away, but the "Save Screenshot" window remains, although I can't interact with it. If I hit Esc on that window in this state, it will close.

Steps to reproduce the behavior

Hit the PrtSc key

MATE general version

1.26.2

Package version

I don't know what package this is. The Screenshot application seems to work fine, but it's not bound to PrtSc.

Linux Distribution

Fedora 37

Link to bugreport of your Distribution (requirement)

I don't know what this means.

PrtSc key What does that mean?

I don't know what package this is. The Screenshot application seems to work fine,

It's mate-utils

[raveit65]

Hmm, the print key does nothing on my f38 box with =>mate-1.27 weird.....

[raveit65]

But i do not get your error dialog.

[spartanhooah]

PrtSc is the Print Screen keyboard key on my laptop. I guess it's not always the same; my external keyboard has PrtScn.

[raveit65]

The command was disabled at my box for some reasons. Now the print button works and i can save the screenshot. What's the output of this command? gsettings get org.mate.screenshot last-save-directory Does it link to a valid directory?

[spartanhooah]

The output is ''.

[raveit65]

Try set a valid dir, eg. gsettings set org.mate.screenshot last-save-directory 'file:///media/Run-Progs/Schreibtisch' (this is mine).

[spartanhooah]

I set the value as file:///home/spartanhooah/Downloads but the error still happens.

[raveit65]

And the gsettings get command shows the new dir?

[spartanhooah]

Yes.

[raveit65]

Does it happen when you use mate-screenshot -i from terminal?

Ok, i need to boot a f37 box and i will try to reproduce the issue

[spartanhooah]

Yes, mate-screenshot 1 has the same problem.

[raveit65]

Was there an update with libpng package in f37?

[spartanhooah]

dnf history list libpng only provides one line, from November 2022.

[raveit65]

Or any other package which can be related? I guess mate-screenhot was working when you installed the system, or you can recall last time when it was working. It must be a reason that it stops working from one of the other day.

[spartanhooah]

I actually haven't tried to use it until today, so I have no idea if it used to work.

[raveit65]

In an updated f37 VM mate-screenshot -i and saving the screenshot works fine.

[spartanhooah]

Huh. I wonder what else could be interfering.

[raveit65]

Maybe add a new user account and try it there. Sometimes something in home dir can be cause such an issue.

[spartanhooah]

A new user has the same issue.

[raveit65]

What graphic card are you using?

[spartanhooah]

Intel HD Graphics 4400 (integrated)

[raveit65]

Do you have another box with different grahics? I am using amd Ryzen 5000 (integrated), but i don't think that this can cause the issue. I do not have another ideas what can cause the issue. Can you edit report header please? It has nothing to do with using a keyboard command.

[spartanhooah]

Title updated. I can try later today with a live USB, if I have time. Nothing else with Fedora actually installed, currently.

[spartanhooah]

I couldn't find a quick way to download the live installer for Fedora 37, so I updated my laptop to 38, and now the behavior is fixed.
