Some plugins freeze in Cubase 7.5.20

Hi guys. I don’t know if you have noticed that some plugins freeze when you load it in Cubase.
For example: FiltherBank3 of Tone2. You can not even move the parameters. I also think Cubase has GUI problems yet.
If you open the stereo out channel in the send section, you will notice that you can’t see the bypass bottom very well. You can see the picture in the link below. This is signal that something is wrong. Thanks guys

What do you think?.

I have the same issue with many third-party plug-ins.
Is there any solution?
