Lightroom Masking flickering

[davidl59950599]

When I create a mask and use any of the sliders when zoomed in to 100% the image flickers in and out.  Any ideas?  I am using MacOS  Thanks!

Also I am using the latest update V8.3

You'll need to provide more information re hardware, etc. Best approach is to provide a copy of the Lr 'System Info'. You can obtain this from the Help > System Info menu item. Note that the System Info dialog includes a Copy button at the top right corner. Pleasse use this to capture the info, then paste into your next forum post.
