I have noticed a bug that AMD Driver 15.7 is causing on Windows 10 build 10240.
The animation/transition on app opening is laggy and stuttering. If you start Windows in safe mode (without any graphical drivers) the problem is absolutely fixed so I'm pretty sure the responsible is the amd driver.
Is that a known bug? Is there a way to fix it or should I wait a driver update?
The word is a new driver will be available around the time of the official general release of Win 10....5 days from now.
