Hello Yves-Alexis I had an idea: possible, that the refresh problem is only observed with the low resolution of my netbook (1024x600). So, i connected the Netbook to a flat screen with Full-HD resolution.
--> The refresh problem is detected with 1024x600 and with 1920x1080. This is only for your information. Regards Bernhard
