Tonelib GFX plugin crashes on certain presets under Linux

    Dear support,

    First of all, thanks for enabling a Linux version of your guitar effects software. That, and the sound it has were the reasons that made me purchase it.

    The linux version of the plugin however crashes when certain presets are loaded. A preset that crashes is for instance the "02D Comfortably Torpid".
    Carla can handle the problem in the "carla-git" version (namely it works), but not the default released version (luckily the plugin crashes but carla survives). At crash time it logs:

    Carla assertion failure: "unlocked" in file ../utils/CarlaSemUtils.hpp, line 182
    waitForClient(process) timed out

    Ardour6 crashes along with the plugin saying in the command line:
    Emulate VST Bypass Port for ToneLib-GFX
    dispatch_x_events: ConfigureNotify cfg: (1200 656) plugin: (1200 656)
    The Tonelib GFX application works fine without problems on those presets.

    Please let me know if I can help dig out this problem with more information/logs.

    In Ubuntu Studio 20.04 (X-fce WM; 5.4.0-72-lowlatency kernel) I am having the same issues in the standalone ToneLib client with some presets (e.g. "[11C] High gain lead"):

    The whole desktop freezes for 5 - 10 seconds and starts running again for 5 secs until going back to freeze (in repeat). When switching to another (e.g. empty) preset not freeze is happening.

    ToneLib Amp Emulation Sound works while freezing, i.e. I can play. The ToneLib-GFX process is in "S" state while freezing. ToneLib does not produce any log to the terminal which is indicative.

    I would be very happy if anyone could shed light on this and how to fix that issue.

    I'm using Fedora and I have the same issue.
    Tonelib GFX works fine in standalone, but in ardour6, if I choose some preset, or for example, if I choose the "Bass IRs Cab", it crash
    Unknown error...
    terminate called after throwing an instance of 'Jack::JackTemporaryException'
    I love this vst, it has a great sound quality. But I need a full fonctional application. I wanted to purchase it, but I 'm gonna wait before it's resolved.

    Actually I assume the error described here is GTK related because the sound still works.

    I recently bought ToneLib GFX because while initial testing in early April I did not experience problems. Might it be related to the current version? Is it possible to download older versions as deb?

    I try again tonelib gfx this day and I see: some presets crash, but if you run tonelib gfx vst with carla, it doesn't crash.
    I don't know why it works with carla but not with ardour
