Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue?
Thanks for you post, I try to change Graphic Processor and the initial problem in the last picture is solved.
But the problem an the add on remaning.
The Tony Kuiper panel V4 not open but existing!Is difficult to explicate but see the picture.
But if i try to clik random the function of panel, it operate!!
If I click random panel and move by mouse this is the result!
Conclusion, the panel is ready but have a graphic problem!

Unfortunately that is no proper solution as it invalidates GPU dependent features (like the Rotate View Tool for example) but it indicates problems with the GPU driver or the OS.
What are your OS version and GPU?
As for the »Tony Kuyper« Panel (or plug-in/…) you may have to contact its creators.
Do they state it works with your current version of Photoshop?
