Created attachment 178891 [details]
weird embedded text files, there are about 40 of those in the one doc that crashed
Okular uses 6,8GB RAM with these 2 documents loaded
Also, the lockup of the desktop happened before the Okular window appeared, I only saw a bouncing Okular icon
One of the PDFs has a bunch of embedded files called "folder.joboptions". Opening them, they seem to just be text files with random content in them.
I can attach one of them.
This might be document specific, but without the documents I'm not sure we can do anything about it. Though it shouldn't be able to crash the computer. If you can't share the document publically, you can try throw it at my email at sune@kde.org Created attachment 178894 [details]

Product Name: ROG Zephyrus G16 GU603VV_GU603VV System Version: 1.0 When can you reproduce the memory leak? Do you have to open both PDFs? Can you reproduce the memory leak with a new user account? I am trying to debug the app, but get a weird gdb issue https://docs.flatpak.org/en/latest/debugging.html followed the docs, entered the container and ran gdb /app/bin/okular (gdb) run "/app/bin/okular": not in executable format: file format not recognized when passing the file I want to open, it tries to execute that file instead, as it does not want to see Okular as an executable program ------- when launching okular flatpak now, and opening that file with ctrl+o, it just hangs and does not do anything other apps start crashing too, I cannot open systemmonitor Update... now Gwenview crashed too, when opening a gif. Reboot, Celluloid flatpak crashed too. Weirdly, GNOME Papers (PDF Viewer) worked well. I think this IS a kernel 6.13 issue, I will open an issue with Fedora. On 6.12 is works normally |
