The picture has attachments for both Breeze Light and Dark theme and the black shade can be clearly seen.

STEPS TO REPRODUCE :-

1. Go to Settings > Appearance > Application Style > Configure Breeze > Go to Transparency Tab
2. Change the "Menu" transparency from Opaque to any value.
3. Open Dolphin & click the Hamburger Menu.

OBSERVED RESULT :-

The Hamburger Menu's background has a black shade and the Blur and Transparency effects are not applied. But the other sub-menus of Dolphin respects the Blur and Transparency effect. 

EXPECTED RESULT :-

The Hamburger Menu should follow both the effects like other menus does.


SOFTWARE/OS VERSIONS :-

Linux : EndeavourOS (Arch based)
KDE Plasma Version : 5.23.5  
KDE Frameworks Version : 5.90 
Qt Version : 5.15.2

I can comfirm  that I am having this issue as well. Fedora 36 Plasma version 5.25.3.

Another thing I notice is that when I take the transparency under Application Style for Breeze down about halfway or more, highlighting a menu option leaves it highlighted after I hover over it.

Confirmed this on Plasma 5.27.4 as well.
Just a slight difference is that the Dolphin's sidebar context menu (accessible by right-clicking any item on the sidebar) menu is opaque.
