Bug ID: 413476
Summary: Wayland/Pipewire segfault on connection
Product: krfb
Version: 19.08.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: grundleb...@googlemail.com
Reporter: t...@r.je
Target Milestone: ---
SUMMARY
When a connection is received, Krfb crashes when using wayland/pw plugin.
STEPS TO REPRODUCE
1. Run Krfb on Wayland
2. Try to connect with KRDC
OBSERVED RESULT
Krfb accepts the login, asks for authorisation and once authorisation is
granted, Krfb crashes. Log as follows:
$ krfb
found plugin at "/usr/lib/qt/plugins/krfb/krfb_framebuffer_xcb.so"
Loaded plugin with name "xcb"
found plugin at "/usr/lib/qt/plugins/krfb/krfb_framebuffer_pw.so"

Loaded plugin with name "xdp"
Segmentation fault (core dumped)
EXPECTED RESULT
Linux/KDE Plasma: Arch / 5.17.1
(available in About System)
KDE Plasma Version: 5.17.1
KDE Frameworks Version: 5.63.0
Qt Version: Qt5 5.13.1
Krfb version: 19.8.2 (not in the list above)
ADDITIONAL INFORMATION
It is very difficult to find documentation on what is required to get this
working on wayland so I may be missing something.
On the host, I have installed pipewire and started the service. The log says
says "Couldn't select sources for the screen-casting session" which suggests I
might be missing something.
I am also running 2x 4k displays with a desktop resolution of 7680x2160 which
may be a higher resolution that something in the stack supports.
