Instantaneous crash on Screen Grab

Bonjour,
On Dell G3 150, Core i5,
on Ubuntu 24.04.1, on Wayland (and I don’t know how to go Xorg ! as the is no more on the account connexion screen!)
Floorp Browser | v11.18.0 ~ v11.18.1, on Kdenlive Version 24.08.1

I have an instantaneous crash as I use Screen Grab,

With this log:

I have to mention that I have recently upgraded my Ubuntu into 24.04.1.
It has been terrible. Several days to make my PC usable!!!

I have run that:

Thank you in advance if you can give me some tips :).

Nice Sunday, José

Hi, and welcome to the forum and community.

Can you check whether the issue described in the official Kdenlive documentation of the Screen Grab function applies to you?

Thank you for your time.

I imagine you are referring to the Hint (in green).

Same crash with Screen grab widget with Project bin tab.
Impossible to put the widget with Clip monitor tab.

Give a time. I will see the other points (X11, x246 with audio…)

Thank you for your time, José
