thanks…
What I understood in yesterdays Q/A is, that ther is a step forward with a new planned feature.
The plan is that we get in a first step a experimental feature ( “low power mode” ) which we can enable with help of the dev-tool and which should reduce the system-load in menu ( hopefully only within the menu 
).
It sounds like a more complex solution as just offer a setting where can disabling all effects in menus and so I’m excited to see how its work.
