Brightness discontinuity on auxiliary display

[Vlada]

When using Genos 2 now I have noticed that there is a discontinuity in brightness on the auxiliary display, where half of the display is brighter and half is darker. There is a clear border in the middle, as if it were two displays side by side. 

Does anyone have a similar problem?

It's been like that on my Genos2 since the very beginning, but it doesn't affect the clear visibility of the printed values.
