Plug-in missing and other bugs

I had some missing plug ins in Cubase 8 and not in Cubase 7.5 all plug ins from
Sonnox
SPL

Izotop make Cubase 8 crash but i fix it with removing all .vst3 in my library/audio/plug-ins

Sometimes I have a big noise with that message (it’s the first time I have it since cubase 5)

“Process received an invalid buffer size, see log for details
Error ID 30800”

I can’t select tracks in the mix console with the mouse, i need to make it in the projet and after to open the mix console

Some plug-ins have a problem to appear correctly their are minimise in a small window, when i click on it, then it appears normal

I just got this…did u find a solution?

hello, I have lengthened the latency in my sound card settings and the error message no longer appears. I went from “normal” to “low” latency
