Mouse curser movement over Waves GUIs

I have just bought a couple of Waves plugins - MixCentric and the L1 Limiter. Both sound great, however, when the mouse curser moves across either of these VST's GUIs there is a whole lot of distortion. If I deliberately "wave" the curser over the GUI the distortion is constant. Move the curser away and everything is crystal clear again. This does not happen with any other VSTs. 
 
Any ideas? I notice that I can use the mouse wheel to control rotaries, which is great - can't believe it is related to that? 

Marshall,
 
I've never seen that.
 
Larry may have the right of it.

Thanks - it is a new all in one HP, i7 6700, 16GB machine. Only had it about three months and it is an amazing PC for music, very quiet and the graphics are stunning - I mean SPLAT looks super crystal clear on a 27 inch display. The fact that it is only happening with Waves plugins is the weird bit. I have sent a note to Waves support. 

I also have a 27". Man I won't want to go back for nothing!

Thanks. I am still trying to sort this issue out. I spent two hours on the line to Waves support last Wednesday night (they called me back). They tried everything, and eventually they isolated the issue to the Intel graphic adapted driver, that neither I nor Waves tech could update - it just produced an error message. I have two graphic adapters and the AMD driver updated without an issue.

They told me to contact HP who have said they are looking into it and will call me tomorrow.

As things stand, it is worse than before Waves support got involved, in that Sonar now crashes every time within a minute or two of loading a Waves plugin, but is 100% stable if I don't use their plugins. Currently, and on Waves advice, the Intel graphics adaptor is disabled. To be continued.

Waves support probably had you do this, but in case they didn't:
 
Marshall, are you sure you have the latest Waves Central install correctly?

They took control of my machine for the duration of the call, and I did have it installed correctly, but they reinstalled it anyway during that call.

Marshall, do you get this resolved?

The short answer is no. I am now getting crackling over non waves plugins too, and have posted about it in the main Sonar forum.

Cheers, Bill

Glad you found a work around. I think there is more to it than the TH3 plug, but if that is working for you, keep on using it (or not using it as this case may be!) 

Just to let you know Marshalll, I tried to reproduce your problem with TH3 with my home pc, but could not. Made a kool little bit of song out of the process though!
