Screen Refresh - Slows down after time

[cjonesmn]

I can't seem to resolve this issue after going thru all the recomendations, etc...
I use two monitors with Lightroom Classic both connected to a GeForce GTX 1060 6GB card via HDMI. I have a PC tower rnning Windows 10 64 bit.

When I'm culling thru hundreds of photographs, the screen refresh gets wonky after about 15 minutes. What then happens is that my screen starts to cycle thru all minimized open windows (including Lightroom), one at a time. This only happens when I'm running Lightroom. I'm not sure if it's refresh issue or what, but everything runs really slow at this point and I'm forced to close the app and restart it.

I disabled the graphic acceleration fearure in LR to see if this had any impact. It helped, but I'm still bumping into the issue to a lesset degree. Any suggestions. Is there a utility I could use to pinpoint the issue? I've spent a great deal of time trying to figure this one out, any help or suggestion would be greatly appreciated.

Any suggestions on who/where to go with this issue? I'm suspecting an issue with video or network devices, BUT I can't pinpoint the exact suspect yet. LatencyMon software points to latency driver issues in dxgkrnl.sys (DirectX) and nvlddmkm.sys (Nvidia), but the actual cause may be something else that is utilizing these drivers. Again, this issue only happens when I preview/cull a days worth of shooting on a 2nd Monitor with Lightroom. I'm not even in Develop mode when it happens.
