--- Comment #6 from Paul paulalbertdev@gmail.com --- Wow, that's very nice you found out the origin of the problem, thanks a lot ! I don't know if there is a link but I've already seen with previous version of wine that the tooltips were not shown at the right place... May I add, as a simple enduser, that this project vst-bridge is not updated anymore but is very convenient for me cause some other VST plugins don't run with the other bridges systems I tried...
