Description
### ~~Bug explanation~~ Feature Request
Hi and Thanks for your awesome library :)
Trying to implement my first WPF project (a media player) based on Material Design but I'm having a lot of performance issues.
The serious one is with ListBox / ListView when the mouse is over which I will try to investigate further by customizing the templates.
You can reproduce it easy with the DemoApp Lists and check your task manager (add GPU column).
I have also other performance issues mainly on full screen with a drawer (seems related to #1116).
Regards,
John
### Version
4.6.1 and latest beta
## Updates
1. Even when I use materialDesign:ListBoxItemAssist.ShowSelection="False" and it will not happen anymore mouse over but it will happen on mouse click
2. It looks like it is also affected by WindowStyle="None" ResizeMode="NoResize" AllowsTransparency="True"
3. OK it's the ripple and visual states but again I think it's not normal (still looking and possible will close this)
4. Closing this but ideally I should be able to use some basic mouse over and ripple with low resources

Research direction
Start with the DemoApp Lists reproduction and inspect the ListBox/ListView behavior around mouse-over, selection, ripple effects, and visual states. Compare the performance impact of the current visual-state approach, including WindowStyle="None" with transparency; done would require a clearly scoped low-resource trigger-based option and a way to verify the improvement.
