[BUG] setLatencySamples crashes Ableton Live 10 (VST3) [FIXED]

[pflugshaupt]

This also seems related to this other thread where I complained about parameter name changes triggering kLatencyChanged component restarts. The whole latency change and updateHostDisplay() mechanism is currently not done well in the Juce vst3 wrapper.

VST3 parameter name changes don't work

Since this patch has been added I tried to update my plugins to report changed parameter names to the host for vst3. While this does work, there is a big issue with UpdateHostDisplay() and void audioProcessorChanged () that gets called by it in the wrapper. The problem is this line: componentHandler->restartComponent (Vst::kLatencyChanged | Vst::kParamValuesChanged | Vst::kParamTitlesChanged);| It means every time I change a parameter name, the host thinks latency changes and latency changes l…

Right now we have crashes from changing latency plus processing gaps from changing parameter names in some hosts. The wrapper really should be much more clever when it comes to calling restartComponent and only send the flags that are really needed!
