Strange VPCZ Screen flickers on Intel

Hey guys,

the last time I experienced a strange screen flickering when contrast is changing and being in stamina mode on my Z11. It happens often when switching between windows and it is quite frustrating. There is an easy way to reproduce that on your machines for testing:

Go to paint, select the paint bucket and the darker grey color in the color palette (upper row, second column) as primary color and white as secondary. Now maximize the paint window and fill with grey (left mouse button) and then with white (right button) continously. When changing to the dark grey, the grey area has a slight but quite noticeable flickering for about 1 second (like 10Hz flicker frequency).

The issue is independent of the brightness, the energy saving mode (40/60Hz) and 16/32bit color modes. When running on the nvidia, there is no flicker. I am running on the latest official drivers which were released when the Z13 came out.

Anybody else having this issue?

 

^your problem is the intel graphics display power savings technology disable it in the intel graphics applet.
