Presets preview problem.

[rzuf]

Hello. Do you also have a problem with previewing presets in the lightroom? The problem is very annoying when I hover the mouse accidentally on presets list, the preview is already in the picture, it hangs. Maybe the option to disable preset preview on the main window would help. I can't work normally at this time. Thanks for help.

Please try switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue 

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

You can disable the preset preview in the Lightroom Preferences Performance panel (see below screenshot)
