Hi, Thanks for the feedback. I had a look at the graphic card on the list and yes my card was not there. I was a good card so I thought it would work in most cases and it does so far. Here are my results. 1. Change order of the monitor in the system. Same result. 2.I used studio driver but this happend before I installed nvidea experience and the studio driver. Same result with studio driver. 3. It wasnot on a specific document I could not use the pentool at all. When starting to add a point workingspace started to flicker, white and for some reason blue. 4. My computer is brand new with a new installed windows 10 and illustrator was one of the first program I installed. 5. Since I used illustrator on this new computer the pref setting was new from the start. 6.Turning off GPU did not solve the problem. 7. I installed version 25.0 instead and there it was no problem with the GPU. Well. after a while I noticed the round circles in the end of the handles was gone. Maybe a bug in that version.
