To be fair, in my opinion they're trying to do a reasonable thing by reparenting the native window under the X window. It would be nice if we can provide a stable external interface to make this work.
Yeah, I'm open to suggestions, but I don't know if the vst-bridge dev is still working on it, hence why I tried a workaround as a hack.
An issue was raised already on it yesterday, but no reply so far: https://github.com/abique/vst-bridge/issues/21
Perhaps it would be good to suggest the interface there, to see if it meets his needs. (either way, he'll have to update vst-bridge to use it, though)
