Hello,
I have some more info on that problem, It is linked to the monitor definition, and windows scaling factor.
If I down grade the monitor and graphic card to 1920 x 1080 scalling factor 100%, it is OK
As soon as I switch to full resolution and scalling factor 125% as recomanded, I have the problem.
Remark : the vertical "glitshes" displayed in time line during preview are also linked to the same setup.
I tried all video card different setups available, nothing helps.
Back to 1920 x 1080 it is OK.
Thanks for the help
Hello, I currently find the solution of my monitors problems.
THERE ARE TWO PROBLEMS
1. Panel sizes not saved : It seems to be linked to the monitor definition. the workaround is : DO NOT SET THE AE WINDOW TO FULL SCREEN. If you resize the window manualy some pixels less that full screen, every thing works fine, the panes are saved !!!!
2. vertical black lines in the time line during preview. That's a very old problem linked to the windows scaling factor. Every thing works fine if the scalling factor is 100% if not just apply the workaround defined here :
