Bug 447076

Bug with kmenu transparency.

The hamburger menu became less transparent if the appropriate setting was set in the breeze theme settings. The sub-menu items have retained this setting.

A bug of this kind was observed in dolpin and okular.

In the applications of eliza, the new system monitor plasma, and the discover, the transparency of any menus is generally absent. 

Also, this setting does not apply to the right click menu in the popular google event calendar widget.

There is no bug in qt applications that are not based on kde but have a similar menu. It is also absent in the plasma settings. 

In other styles of design, for example kvantum or https://github.com/Luwx/Lightly, this bug is not observed, from which I conclude that the problem is more likely in the breeze theme, but it can also be in the kde frameworks. 


STEPS TO REPRODUCE
1. Appearance-> application style-> breeze-> transparency-> set any value other than the maximum, well replaced already at 80%.  Apply.
2. Go to dolphin/okular/any kde app with hamburger menu 
3. Look.
