The option to switch between the light and the dark theme is missing in the general settings under "User interface". On the 2.6.0-beta1 it was available. See screenshots.


The possibility to change the application theme from light (seems to be default) to dark.
Nothing. Besides the fact, that the icon bar is also buggy, may be related (see #4963).
