I am having serious problem with Windows 10 (Got the upgrade). Everything runs fine apart from trackpad where it will randomly lag and sometimes when you click the start menu it won't appear it will be transparent.
My laptop spec;
AMD A8-3530MX 1.90GHz
AMD Radeon HD 6620G
8GB RAM DDR3L
120GB SAMSUNG SSD
I have tried AMD drivers from AMD directly and tried it using the Microsoft device manager. It's the latest 15.7.1 drivers. Updated trackpad drivers. Used older version of trackpad drivers and AMD graphic drivers. I have even done a clean install.
I am guessing AMD are not aware of GPU issue with regards to some APU?
