Debian version of swaylock (based on v1.5) in bullseye (currently testing branch) crashing
In my current setup swaylock crashes for me when waking up my computer. I see the ring, start typing and even before hitting the second key I already see my desktop - and swaylock having crashed in the logs.
I know it's not swaylock vanilla, though the 3 patches applied to the source for the debian package don't seem invasive (http://deb.debian.org/debian/pool/main/s/swaylock/swaylock_1.5-2.debian.tar.xz) and since its single purpose is to lock the screen which it fails to do so in my case, I allow myself to also report it here.

I have built with meson build/ -Db_sanitize=address,undefined and will the use the resulting binary for some time in an attempt to get more information. In order to capture the output I am going to run swaylock like swaylock &| tee swaylock.log. Let me know if I should change anything.
Already I see without a crash a couple of memory leaks like
Direct leak of 256 byte(s) in 1 object(s) allocated from:
#0 0x7f75f6ace279 in __interceptor_malloc /build/gcc/src/gcc/libsanitizer/asan/asan_malloc_linux.cpp:145
#1 0x7f75f5883255 (/usr/lib/libfontconfig.so.1+0x21255)
I think this is benign and happens because for leak detection to work properly libraries would have to be compiled with asan as well. Mentioning it just in case.
I just compiled with the instructions in the readme with the extra options to meson build. It is easy to compile and my binaries probably won't work on other systems anyway (not sure if they are static). So I think it it is better if you try building yourself.
Hi,
Same issue with swaylock-1.5-2 as shipped by Ubuntu 21.04. Recompiled from master branch: crash when secondary monitor wakes up seem to be solved!
swaylock built on Debian 11:
meson build/ -Db_sanitize=address,undefined
Upon exit:
==196107==LeakSanitizer has encountered a fatal error.
==196107==HINT: For debugging, try setting environment variable LSAN_OPTIONS=verbosity=1:log_threads=1
==196107==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)
==196108==LeakSanitizer has encountered a fatal error.
==196108==HINT: For debugging, try setting environment variable LSAN_OPTIONS=verbosity=1:log_threads=1
==196108==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)
Update, with the same binary, when laptop left connected to an external monitor via USB-C, swaylock gets "stuck" consuming 100% of the single core. It does not respond to any user input and shows no widgets on the screen. The only way out was to kill it from another TTY.
Another update, I can reproduce the same when running Sway v1.6. Installed from experimental together with:
