Latest builds of ACE, Bazille, Diva, Hive, Satin, Zebra 2/HZ (beta) crash on opening UI on Arch Linux

[superjudge]

I am running a fully updated version of Arch Linux, where all of the mentioned U-HE plugs have been working before updating to the latest versions. Currently, the status is as stated below; I am guessing something common in the GUI code got introduced in the latest builds, as they all seem to be crashing in the same place.

The stack traces are from running the plugs in Carla, as that was the quickest way to systematically test all of them. I have tried them also in the latest versions of Bitwig, Renoise, and Reaper, and they all crash there as well.

When loading them into Carla, the plug GUIs are not opened initially, and I can then play the plugs and change parameters through the Carla interface, but as soon as I try to open the plug native interface they crash (logs below).

The stack traces below are from running the vst3 versions, but they all crash in similar ways for vst2 and clap.

Arch Linux is running glibc 2.40+r16+gaa533d58ff-2

I hope this information helps. Please let me know if you want me to do some additional tests.

Hmm, we did update the dialogs recently to work more consistent on all platforms, that's the only significant change I can imagine that might lead to issues in some Linux distributions.

I'll create a ticket for this, but it might take a while.
Our main Linux guy is not available for some weeks.
And we are not testing our plugins on Arch Linux, as they are mainly built to support Ubuntu based Linux distributions.
But we'll look into it, if we can manage to set up an Arch Linux system.

It's either the dialogs.

Or it could also be related to the preset database. The database starts scanning for presets the moment the plugin GUI is opened. If the plugin cannot access or create the database due to permission issues, this might cause trouble.

You could create a new folder on your desktop and call it u-he-log.
Once the folder exists, reproduce the issue and immediately afterwards zip the u-he-log folder and send it to our support.
We could then check if there is anything suspicious being logged.

[superjudge]

I did the log-thing you suggested and submitted the log-file to your support. Please let me know if there's anything else I can do to help figure out what's wrong!
