Crash when connecting from RealVNC to Raspberry Pi

[noafterglow]

wayvnc crashes on Raspberry Pi 4 model B when connecting from RealVNC Viewer 7.12.0 (r14) x64 (Jun 12 2024 12:33:32) After I enter the password a black screen pops up and instantly disappears.

uname -a

wayvnc when run under systemd as deployed in the standard distribution crashes. Log file in journalctl is extremely unhelpful, "Segmentation Fault"

If I stop the service, and run wayvnc as the currently logged in user, then it works fine. Adding --render-cursor --gpu it still works

If I connect wayvncctl with the -v option when running under systemd I get the following, (also kind of unhelpful)

Happy to run any other tests you all need, but not sure how to gather more info while running under systemd.

It would be good to see the output from coredumpctl info wayvnc. If this started happening after an upgrade, it might be a good idea to revert the package and see if the problem goes away.

[noafterglow]

This was a fresh install.

coredumpctl was not installed. I installed it. Now the situation is different. It still crashes, but now it restarts and reconnects (successfully). After the first time, it reconnects without crashing... So this seems to be a timing issue of some kind.

Can you install debug symbols? It would make those backtraces more useful.

The command is apt install wayvnc-dbgsym aml-dbgsym libneatvnc0-dbgsym

Thanks for the backtraces. I have not been able to reproduce this myself.

Did you run apt update && apt upgrade after flashing the sdcard?

[noafterglow]

It ran as part of the install process. its only been about 2 weeks. I just did it again, and these packages were upgradable:

gir1.2-gtk-3.0 gtk-update-icon-cache gtk2-engines-pixbuf libgtk-3-0 libgtk-3-common libgtk2.0-0 libgtk2.0-bin libgtk2.0-common pipanel raspberrypi-sys-mods wpasupplicant

after upgrade no change.

I did notice that right now what happens is that it dies initially more slowly...
First, the window comes up, then it turns black, then it shows an error something about the connection. Then the window disappears, and comes back, black again... then it shows something about a bad rectangle seeming to indicate that its bigger than the screen size.

Journal does not show anything particularly useful.

I see that it most often crashes when encoding a raw frame. This means that your client chose raw encoding. What happens if you tell RealVNC viewer to use ZRLE?

Does the same thing happen with TigerVNC client?

[noafterglow]

here's some additional info. I recorded the video of startup . This only happens AFTER coredump was loaded. before, it just died before the original black screen showed anything.

https://github.com/user-attachments/assets/9811854d-0e5f-4f1c-84d0-a4af721673f5

[noafterglow]

how do I tell realvnc to use ZRLE? I don't see that option. TigerVNC does not crash wayvnc.

[any1]

how do I tell realvnc to use ZRLE

properties -> expert -> preferred encoding.

It's actually the default. I'm not sure why RealVNC goes to raw.

If you edit, /usr/sbin/wayvnc-run.sh as root and add an argument to the wayvnc command to enable trace logging, we might see more useful information in the journal. The argument is -Ltrace.

[noafterglow]

The default preferred encoding was ZRLE2.

[noafterglow]

Switching to ZRLE from ZRLE2 as preferred encoding solved the crash issue. Not sure if it solves it from raw install, but it does seem to prevent the crash now. So there appears to be an issue with realvnc using encoding ZRLE2 as preferred which crashes wayvnc probably during some form of negotiation.

[any1]

RealVNC switches between encodings rather rapidly right after connecting. This is probably just a use-after-free in the raw encoder.

e14fc5ac801e43c5f44cadf5936a688d63f5be9a should fix it.
