Can you try loading the plugin in the Windows version of REAPER running under Wine and check if it does the same thing? I'm fairly sure it would also crash in the same way there. The crash is likely not an issue with yabridge.

No such issue with Wine 9.1

[aaaaaaaaargh]

The exact same problem happens on every Wine version I've been trying so far, starting from 9.1 up to 9.6

Been throwing my head at this all day, and I can safely say it's probably not a yabridge issue. The Windows version of REAPER via WINE also exhibits the same behavior.

If I had to speculate based on the info the terminal gives me (and that's about all I've got right now,) it's something to do with rendering. The GLSL shaders are complaining a lot to WINE, and while I'm not sure they're all relevant, the fact that the fault occurs when we try to make the window go away certainly gives it that smell. BIAS FX uses CEF for its user interface, and CEF apps have been noted as problematic.

That being said, it is weird that this only happens with the VST3 version.

If I happen upon a workaround, I'll let yous know. I have a couple ideas.

UPDATE: It's Positive Grid's fault, surprisingly! The latest version of BIAS FX 2, 2.7.0, is just all kinds of broken as it turns out. BIAS FX 2.6.1 works great. Shoutout to this Reddit thread. https://www.reddit.com/r/PositiveGrid/comments/1e3wfg7/comment/le9fbzo/
