This is partly a regression that was introduced during the KF5 port. Partly because the KDE 4 behaviour is kind of erratic already (background colour shown but theme selected in dialog). I really have to dig into the KConfig dialogue. Several games do have problems with it.
Git commit 68bd2b02ce2cfe9e320587f46584843d70f847f5 by Frederik Schwarzer. Committed on 24/02/2016 at 02:32. Pushed by schwarzer into branch 'master'. Fix background config dialog page. I could not make it work with the Enum so I used hree Bools instead. It's more ugly this way (code-wise) and if someone knows how to make the Enum work, please speak up. Thanks André Marcelo Alvarenga for the report.
