New Why is the lower border region flickering while some apps are open?

[Studi1]

Some apps touch the lower border region when open. Then the lower border region (region with the 3 standard commands to return 1 app level up, to close the current app etc.) is flickering heavily sometimes in vertical mode.

How can I stop the flickering?
