Lightroom Classic issue: Gets lighter/darker when hovering over Loupe or clicking on sliders.

I haven't been able to find any mention of this online, so I am assuming this is a bug. When I hover in and out of the loupe, the image keeps switching between slightly lighter or slightly darker. The lighter and darker versions also toggle when I click on any of the sliders, and when I move a slider it rapidly flickers. I am not using presets or doing anything with presets, and I've turned off camera calibration just in case (these are scanned film negatives anyways, so no metadata). My lightroom classic is up to date.

I've attached a gif showing this.

Greetings Culver,

You don't mention what OS you are using or what graphics card you have. 

This looks suspiciously like a GPU issue.  If you go to Preferences > Performance and uncheck GPU do you still see the issue?
