Issue

When you move the mouse pointer over any preset in the Presets panel (Develop module), Lightroom Classic CC displays its live preview in your photo in the Loupe view. The live preset preview feature─introduced in the April 2018 release of Lightroom Classic CC v7.3─is slowing down your computer's performance.
