Wonky monitor behavior

I have a three-monitor set-up running from my Surface Pro 3 - one HDMI and two USB-VGA adapters. I've not had this problem until very recently. From time to time, and I can't determine what prompts it, the left-most portion of my center screen will suddenly appear in the left screen, like it is split. For that short period of time, the left screen becomes unresponsive to mouse-clicks. I can't seem to grab a screenshot of it either. It's become quite annoying.

I don't have any unusual or highly customized settings.

As I mentioned, I have been running three monitors in this setup since at least 2016 without issue. Any ideas?

Thanks in advance!!!!

That's really strange! I've never run into that before either, almost sounds like the USB adapter is flaking out. When you try to take a screenshot, does the screenshot just look normal even though the screen itself is bugging out?

Yes. It's only on one monitor, also. It either corrects itself, or I have to move the open window to make it disappear. Everything else seems to be fine. What's odd, is that the left portion of the center window that bleeds over is just a mirror - if I move the mouse in that portion of the center window, it's duplicated. I did enable minimal logging, if that might help?

I don't think the logs would show anything, no. If you exit DisplayFusion when that issue occurs, does it immediately go away?

So I've swapped the USB adapters, and the issue stays on teh same monitor. Therefore, it doesn't seem to be the USB adapter. It's so random, I can't even determine whether quitting DisplayFusion affects anything. Generally, if I grab the active window on the affected monitor (which is the far left monitor), I can essentially shake it or resize it and the problem disappears.

Super weird indeed! I'm not sure what else to try, aside from swapping out the monitor itself. I've never run into a bug like that with DisplayFusion, so my best guess would be either a monitor issue, or a video card driver issue.
