Calf Studio Gear plugins crashing on GNOME/Wayland

Grrr of the day: The excellent Calf Studio Gear audio plugins crash Audacity, Ardour, and Qtractor on GNOME/Wayland when you add them to a track. So my otherwise successful Wayland experiment has ended for now and I am back to KDE/X11 where the plugins work as expected...

I can't yet see the bug report that you've filed smile .....

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

There were no error messages to report anywhere I looked in the logs or the terminal, just naked, not immediately helpful application core dumps. And strangely enough the plugins work fine in Calf's included host on Wayland.

So I am not even sure if this is a bug in the plugins or Wayland or the DAWs. Maybe I will investigate this more later. I will have to comb the desert for error messages. smile

Re: Calf Studio Gear plugins crashing on GNOME/Wayland

You could run them in gdb.
I assume the problem is https://www.archlinux.org/packages/comm … 6_64/suil/

Re: Calf Studio Gear plugins crashing on GNOME/Wayland

OK, here are Qtractor and Audacity stack traces. (Ardour does not actually seem to have produced a core dump.)

@Morn, this conservation is now heading into support question area. Feel free to continue the conversation here and edit the title if you can think of something more appropriate.

Re: Calf Studio Gear plugins crashing on GNOME/Wayland

So should I file a bug report at the Suil bug tracker then? Although in the stack traces I do not see anything specific about Suil being the problem here.

Re: Calf Studio Gear plugins crashing on GNOME/Wayland

Audacity crashes in the crash dialog … for the same reason as the original crash (apparently "_ZN15AudacityProject13FixScrollbarsEv"
Qtractor is a more expected suil crash, but interestingly w/ libQt5XcbQpa.so.5 - ie. on xwayland? Do both programs run in xwayland?

Apparently. I think Qtractor even prints something about ignoring the GNOME/Wayland session environment variable in the terminal...

Edit: I'm back  in GNOME now, here is the message from qtractor:

$ qtractor
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

Yes, but it does not work, I still get the same message. Or does this variable have to be set in /etc/environment?

$ QT_QPA_PLATFORM=wayland qtractor

[martin@omen ~]$ qtractor

QSocketNotifier: Can only be used with threads started with QThread

Edit: With the env variable, I now get an empty plugin window in Qtractor. So something is definitely different, but still broken.

No, that's not necessary.

I'm using gdm, so I think that section about starting Wayland manually does not apply here...

Re: Calf Studio Gear plugins crashing on GNOME/Wayland

You could try and take gdm out of the equation(temporarily)
Than try with that piece of code in your shell rc.
Otherwise I'm oOo

Ah OK, that is what you meant. Yes, I could try that of course. smile

But like my edit above says, I think setting the variable does work after all, because now I get an empty plugin window instead of Qtractor crashing. So something is different when you set the variable, but it does not fix things...

Re: Calf Studio Gear plugins crashing on GNOME/Wayland

I don't think suil works on wayland - and calf is gtk2 only.
What for

GDK_BACKEND=x11 qtractor

?
