Bug#1051418: obs-studio: clicking on an xcomposite window source makes obs segfault
Package: obs-studio Version: 30.0.2+dfsg~ Followup-For: Bug #1051418 Unfortunately I can confirm the bug at question with the (not yet uploaded) obs-studio 30.0.2. the OBS shipped by flatpak does not have this problem, so it appears to be Debian packaging problem.
Bug#1051418: obs-studio: clicking on an xcomposite window source makes obs segfault
I'm seeing the same bug in the latest Debian testing updated this morning.
Specifically, if I have the following github page open in my browser clicking
the xcomposite window source cases a seg fault as reported.
https://github.com/pjreddie/darknet/issues/553
This results in a window name of "Error on make: 'cuda_runtime.h: No such file
or directory' · Issue #553 · pjreddie/darknet - Brave"and the name_lower
variable appears to have zero values in the struct which is then pushed to
window_strings.array. I can't currently step into dstr_to_lower().
$18 = {name_lower = {array = 0x0, len = 0, capacity = 0}, name = {array =
0x570b88e0 "Error on make: 'cuda_runtime.h: No such file or directory' ·
Issue #553 · pjreddie/darknet - Brave", len = 100, capacity = 101}, desc = {
array = 0x55c24560 "54525967\r\nError on make: 'cuda_runtime.h: No such
file or directory' · Issue #553 · pjreddie/darknet - Brave\r\nbrave-browser",
len = 125, capacity = 126}}
The following is the gdb backtrace:

Bug#1051418: obs-studio: clicking on an xcomposite window source makes obs segfault
Package: obs-studio Version: 29.1.3+dfsg-2 Severity: important Hi, after upgrading from 29.0.2+dfsg-1+b1 to 29.1.3+dfsg-2 (bookworm to trixie) I couldn't work with the xcomposite window source anymore. In fact, a pre-existing scene that was set up to use that source makes obs segfault immediately when I click the entry in the sources tree, not even able to remove it and finally switch to a pipewire window source (which has its other quirks). I'm on gnome with wayland, I guess that is needed information to reproduce it. When starting obs in the console, the only line that is printed after clicking on the entry is segfault.
