--- Comment #3 from phrxmd <philipp.reichm...@gmail.com> --- Created attachment 153760 --> https://bugs.kde.org/attachment.cgi?id=153760&action=edit Backtrace with KWin in frozen state after brave-browser --tor hangs Here is a backtrace. I'm unsure whether I got it by the correct procedure - I connect via ssh, attach GDB to the kwin_wayland process by issuing `sudo gdb -pid $(pidof kwin_wayland)`, then I set the logging file and `set logging enabled on` and `continue`. When KWin freezes, there is no signal issued, so I stop KWin manually by issuing SIGINT from GDB with Ctrl+C, then I get the backtrace with `bt full`. I noticed that KWin seems to be doing something (just not reacting to mouse events), so I've done the Ctrl+C - `bt full` - `continue` cycle a few times in the backtrace. Also when I detach GDB again, I can kill the brave processes from SSH which frees up KWin again, after which I get a bunch of output in the console where I started Brave: > brave-browser --tor Nov 15 10:04:15.063 [notice] Tor 0.4.7.10 running on Linux with Libevent 2.1.12-stable, OpenSSL 1.1.1s, Zlib 1.2.13, Liblzma N/A, Libzstd N/A and Glibc 2.35 as libc.
