SUMMARY When opening a pdf file, often the *computer freezes* for about a minute. Without any warning or indication. Then computer contiues normally. Of course this is a bad bug. It harms work on the computer. This bug first appeared about 2 weeks ago. STEPS TO REPRODUCE 1. open pdf file 2. computer freezes 3. wait about 1 minute OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Operating System: Kubuntu 24.04 KDE Plasma Version: 5.27.11 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.13 Kernel Version: 6.8.0-45-generic (64-bit) Graphics Platform: X11 Processors: 8 × 11th Gen Intel® Core™ i7-1185G7 @ 3.00GHz Memory: 15.3 GiB of RAM Graphics Processor: Mesa Intel® Xe Graphics Manufacturer: Dell Inc. Product Name: XPS 13 9310 ADDITIONAL INFORMATION On my other computer (DELL desktop) this bug does not show.
It seems that the problem goes beyond OKULAR to other PDF related operations. There is freezing (of varying lenfhth, and not always) also when opening a PDF file in DOCUMENT VIEWER. Sometimes delays when saving a PDF file (say from an email).
The bug is still here. Today interrupted my work twice.
IS it related to a specific PDF file or does any pdffile trigger it for you ?

Happens about 1-3 times a day. Either when opening by OKULAR, or when saving a pdf file from an email to a local folder.

This honestly sounds more like some sort of system driver (filesystem, device, graphics) lockup or bad hardware. Try look at syslog and dmesg and see if anything has been logged there while issue is seen. With the amount of PDF files I open daily when hacking on Okular and Poppler, I don't think I have seen that ever.

I did get some error messages now, in DMESG and SYSLOG. Related to opening pdf files, even though the freezing bug did not occur. Can I upload them?

This is a bug in the intel driver (fixed a year ago in certain kernels; please ask your distribution for a kernel with the relevant fixes) It seems to be this: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/8685

At least now I know where the problem lies. I will try KUBUNTU 24.10, via upgrade route. It comes with kernel 6.11.
