Dim Screensaver “Configuration” screen is bad

Howdy. I just built from git, using:

Code:
git clone git://github.com/xbmc/xbmc.git kodi

as found in docs/README.linux

The distro is Mageia release 6 (Cauldron) for x86_64 on Asus Z170I PRO GAMING using i5-6500 CPU onboard Skylake Intel HD Graphics 530, fwiw.

The result is working better for me than the Mageia kodi-17.3-9.mga6 but there are some niggles.

One is in my Dim Screensaver configuration screen, shown below. The screensaver works, dims to the extent and after the delay as I previously had set it. I didn’t delete any of ~/.kodi files. Does the picture indicate something or is some other information needed? Thanks.
