Hi Toni, sorry for the lame report
Windowed mode is fine.
Changing "display buffer" does not fix the issue.
Not a Laptop. It is a crossfire 2900xt system with latest drivers.
Changing p96 mode in WB does not fix the issue.
I am sure it is a I.D.10.T user error or Driver issue too... But still an real issue till I fix it...
Many thanks.
