Lightroom: Develop module: Graphic anomalies when a slider is moved (mainly exposure)

I resisting the urge to complain about LR's ongoing performance issues (if devs haven't heard the community yet, I don't think it's ever going to be resolved until someone offers a better competitive software)...

My issue is within the Develop module which exhibits graphical anomalies when a slider is moved (mainly exposure). It doesn't happen all the time, but frequently. I thought it might be attributed to using Smart Previews instead of originals (the checked box under 'performance') but turning it off changes nothing. 

What's happening when I move the exposure slider is that my photos turn almost to an 8-bit GIF quality, like a luminosity mask overexposing the image until I release the slider. It makes it nearly impossible to gauge accurate exposure adjustments until the slider is released.

This occurred on my GTX 970 graphics card, then again on my new 1070, eliminating both the card and driver as suspects, imo. 

Anyone else have this issue?

I do see this from time to time but can't reproduce the issue. It is just random.

Rikk, I've got 378.49 I must say that it doesn't happen as often. As a matter of fact, maybe last week I noticed it, first time in a while. I guess they've ironed it out but not quite.

Jerry,  I am running the GTX 970 and the 378.49 driver on my system with a 21:9 3.5 K monitor. I will run some tests and see if I can duplicate what you are seeing.  What is your monitor resolution?

My monitor is running @4K and these anomalies happen randomly when moving the exposure slider...
