I only found ONE way to fix this bug and it's prety easy to do.
AMD features fk up all your games with ALT+TAB etc... So, the best solution is to remove it.
How?
1) Remove AMD Adrenaline from your programs & reboot your computer;
2) Device manager > Display adapters/Graphic card > Select it, right-click and do a manual update.
3) Select the files in C:\AMD\ if you already have downloaded the drivers.
Otherwise, download the drivers, unpack it but don't install it. Then, proceed point 3.

EDIT: you can still update your drivers but you just have to do it manually.
