You are getting this with the VST3 plugin?
Yes I am using VST3
Unfortuantely I could not reproduce an invisible mouse pointer, it stays visible when the plugin window appears (with the demo dialog question).
It was not visible for me when the plugin appeared
I suspect the mouse cursor is handled differently when running things in VM. It's probably rendered by host / hardware ...
I have zero C/C++/wine experience but I was able to compile working wine 8.17 yesterday and I'm now running git bisect to hopefully find the commit that breaks the cursor.
