SUMMARY
I'm developing a Kvantum theme that try to use as much translucency as possible. The theme can be found at this link:

https://github.com/Davide-sd/FlatBlur/


Using this theme, when Dolphin is set to "Details View Mode", the header bar (Name, Size, Modified, ...) is not behaving correctly: as you can see from the attached screenshot, when scrolling down the files/folders list, the file or folder details are going to be overlapped with the header.

STEPS TO REPRODUCE
1. Download and apply the Kvantum theme provided in the aforementioned link.
2. Open Dolphin, move to a folder containing a lot of elements.
3. Switch to "Details View Mode".
4. Scroll down the file/folder list.
5. Observe the header.

EXPECTED RESULT

When scrolling, the list should not overlap the header. A correct behavior is implemented in KSysGuard (System Monitor) -> Process Table. There, you can scroll the process list and the process details do not overlap with the header bar.
