Very slow starting and display of VST GUI

[sm_jamieson]

When a VST editor GUI is opened (show editor trigger on the plugin manager), it can take
a Very long time for the GUI to open (e.g. Omnisphere over 20 seconds on first occasion,
then up to 10 seconds after that. Also use of the GUI is very slow.

I think this is due to the restricted CPU allowed or something (so as not to interrupt the audio flow).
But it makes it very hard to use the VST GUI, selecting presets, modifying settings etc.
I don't use any other DAW than Usine, but in youtube video of other DAWs, the VST GUIs open almost
instantly.

Can we have a mode of giving the GUI more CPU (where we accept the audio might be less reliable) ?

Or there may be some other reason why VST GUIs are very slow in Usine.

Thanks.

I'll try in HH6 and see if this is better.

I confirm that it's faster in HH6
