--- Comment #12 from AndyF andreas.franz@arcor.de --- Thanks, Rémi!
Flickering is gone and picture is back.
There's a little glitch left - picture area (manufacturer call them "split") has a dynamic toolbar. It should be visible, if mouse enters the split - and hidden, if mouse lefts the split.
At the beginning it works fine - but after some playing around, detection of entering the split within the application is gone. Only if you move your mouse from a different application into the split, toolbar will be visible again.
Maybe it's some part of your awesome work?
regards, Andy
