Yes, there is a way to disable translucent drop-down menus in Photoshop. To do this, follow these steps:
Open Photoshop.
Go to Edit > Preferences > Interface.
In the Interface preferences, uncheck the Use Legacy Drop-Down Menus checkbox.
Click OK to save your changes.
Once you have disabled translucent drop-down menus, they will no longer be acceptable. They will instead be opaque, which may make them easier to see and use.
