Cubase 9.5 hangs on project close on Win 10

Post by fese » Sat Feb 17, 2018 10:10 pm

Cubase 9.5.10 tends to hang when closing a project, i need to kill it hard. The weird thing is, after starting C again and opening the same project, everything works normal again. My observation so far is that it does not depend on the project, just after the time I spent in the project, opening and immediately closing works fine, just after some time (more than a few minutes) it practically always hangs.
It is a brand new Windows 10 system, the problem didn't appear on my old Win7 system with the same Cubase version. I have pretty much all the same plugins installed (some might actually be a bit newer than on the old system).

There is still some CPU usage, the screenshot show the sysinternals threads view when the hang happens:

(49.41 KiB) Not downloaded yet
Most interestingly is the State "Wait:Userrequest", seems like Cubase is waiting for some input by me, but there is no window left but the main, and that is completely unresponsive.

Most probably some plug-in or component is not released.

Could you try to create an empty project, wait some time and then close? Does it hang?

Yeah, you're right, most likely some plugin. I had another project now which didn't show this behavior and I just tried and audio-only project with just using cubase channel strip, no problem. It is weird though that it only happens after some time. Or some action, that is.
The problem is now finding out which plugin is the culprit... I'll try using listddls to find out which dlls are still loaded, but if anyone has a better idea, let's hear...

As I still have this problem, I'm gonna bump this thread :)
By taking memory dumps in the deadlock state and looking at a threaddump in windbg, I've narrowed the problem down to the following plugins
Shattered Glass audio's SGA1566 and Tonebooster's plugins (the v3 ones, not the JUCE ones).
I think this is the thread where it somehow goes wrong:

or other TB plugins.
I've opened a call at Tonebooster's, Jeroen was very quick to answer, but sadly cannot reproduce the problem (well, I don't know yet how to exactly reproduce it, except work for some longer time on a project with the mentioned plugins and then close it...)
I've opened calls at Steinberg, but so far all they did was put the blame on a third party plugin (the wrong one).

This problem happened so far with all updates of C9.5 and all revisions of TB plugins this year.

Can i really be the only one with this problem???
