Hi and thank you for the help, but It didnt work. The graphics mess maybe wasnt there at the start but it got worse and worse in a minute… strange. Sometimes its already there at the window, where you choose your project. colors getting crazy. 
colors changes too when i move mouse cursor above the item or box , it’s like im painting them or something…
Maybe its to do with some graphic or display related setup? refresh rate or sync or something?
Last year it worked fine and all i have maybe changed are some display settings for some games to work better…
