This effect is on Linux (Ubuntu 12.04) only. The sliders look different on Windows with MSVC 10 as base for Build.
Within theide I get different sliders when I change Setup->Environment->IDE.GUI_Theme to Classic or Standard.
For my application I didn`t find a selector for GUI theme. But if I check NO_GTK in the configuration flags then the sliders change as well.
The question remaining is: Where does the GUI theme "Host Platform" get the slider thumbs from?
Answer: As GTK theming is applied (the only use of GTK I think) the thumb is retrieved from a gtk_theming_engine residing somewhere in a shared library.
NB.: As theming is based on GTK-2 --what I deduce from the names of the engines handled in the code -- but most applications on my machine use GTK-3 I stopped searching any further. The consequence is NO_GTK (better name NO_GTK_THEMES) or not using standard sliders but those within Controls4u.
