image of visual glitches
(In reply to Tom from comment #0) At least the freezes seem to be related to a GPU (or CPU?) hang. Here another part of journalctl during the last freeze. But I am not sure if this is also causing the glitches and crash or how they may be related. For that the attachments might provide more information.

This is a kernel bug Thanks for the detailed information and logs. If something is crashing, we also need a backtrace. While your session is frozen, can you switch to a TTY and run the following: sudo gdb --pid `pidof kwin_x11` wait for that to load and type: set logging on set pagination off bt quit This will save a file called gdb.txt in your home directory with the backtrace. Please attach that to this report. Thanks! This seems possibly related to bug 471136 based on the logs In those commands, I gave you the wrong process name. This: sudo gdb --pid `pidof kwin_x11` Should be: sudo gdb --pid `pidof kwin_wayland` Apologies for any confusion When it's kwin_wayland, you need to do it while SSH'd in from another computer, because attaching will make it freeze if it's not already frozen! 🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information, then set the bug status to REPORTED. If there is no change for at least 30 days, it will be automatically closed as RESOLVED WORKSFORME. For more information about our bug triaging procedures, please read https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging. Thank you for helping us make KDE software even better for everyone! Hello, thanks for the help everyone! 1. I didn't manage to do the backtrace via ssh after a crash (need another pc), and currently I am not able to reproduce the crash properly. I think this might be because I deactivated some desktop effects and maliit-keyboard, if I manage to figure out what is causing this I will update. 2. The visual glitches (see screenshot) are present on both X11 and Wayland. During the glitches there is actually no gdb stack. Are there other debugging tools to identify the cause of the glitches? 3. I finally managed to get a stack during a glitch which might be the same issue or a separate one. It appeared the moment I clicked on "Open" in the filepicker while trying to share a file using LocalSend (via Flatpak https://flathub.org/apps/org.localsend.localsend_app). Not sure if it's related to the file picker, I couldn't reproduce just now. Here's the stack via GDB: #0 0x000076c258498d71 in __futex_abstimed_wait_common64 (private=30402, cancel=true, abstime=0x0, op=393, expected=0, futex_word=0x7ffc34057cc8) at ./nptl/futex-internal.c:57 #1 __futex_abstimed_wait_common (cancel=true, private=30402, abstime=0x0, clockid=0, expected=0, futex_word=0x7ffc34057cc8) at ./nptl/futex-internal.c:87 #2 __GI___futex_abstimed_wait_cancelable64 (futex_word=futex_word@entry=0x7ffc34057cc8, expected=expected@entry=0, clockid=clockid@entry=0, abstime=abstime@entry=0x0, private=private@entry=0) at ./nptl/futex-internal.c:139 #3 0x000076c25849b7ed in __pthread_cond_wait_common (abstime=0x0, clockid=0, mutex=0x65345d91bba8, cond=0x7ffc34057ca0) at ./nptl/pthread_cond_wait.c:503 #4 ___pthread_cond_wait (cond=0x7ffc34057ca0, mutex=0x65345d91bba8) at ./nptl/pthread_cond_wait.c:627 #5 0x000076c25c0eff73 in ???
