The output when running from a terminal: Initializing D-Bus connectivity with XDG Desktop Portal DBus session created: "/org/freedesktop/portal/desktop/request/1_150/krfb2570626603" Initializing Pipewire connectivity Stream state changed: connecting Stream state changed: paused Stream format changed Stream state changed: streaming [1] 5767 segmentation fault (core dumped) krfb I also tried using `krfb-virtualmonitor`, and it too keeps crashing like normal Krfb. Although, if I never connect a VNC client to it and instead stream the virtual screen using OBS or whatever else no crash occurs. Additionally I tried plain Krfb on an openSUSE Tumbleweed VM and connecting to it using KRDC, and Krfb ends up crashing there as well. Can you retest this issue? There's been changes and as of 6.0.3 I can no longer cause krfb-virtualmonitor to crash nor can I use it to crash plasmashell. krfb-virtualmonitor did manage to last more than 30mins this time it seems, so yeah seems fixed now. |
Created attachment 151609 [details] Stack trace from gdb SUMMARY On Plasma Wayland Krfb eventually crashes with a segmentation fault after some time (under 10 minutes usually), while on X11 Krfb stays working (for over 30 minutes at least) just fine. It seems like the crash does not appear as quickly if there is not much going on in the shared screen. I also tried both allowing remote input/control and disabling it, Krfb still crashes regardless. STEPS TO REPRODUCE 1. Run Krfb on Wayland 2. Connect to the system using a VNC viewer (I used bVNC Pro on Android as well as KRDC locally, same results) 3. Continue working as normal OBSERVED RESULT Krfb inevitably crashes after some time. EXPECTED RESULT Krfb does not crash.
