Is this a Monitor firmware issue, display driver, or a Windows 10 thing? One window is brighter, others dimmer

I have the MSI Optic MPG341CQR and have it connected to two Windows 10 computers via DP and USB-C ports that I alternate between depending on if I'm working or doing personal activities. Both computers have Nvida graphics cards and are running the latest drivers.

Not infrequently when I come down to work in the morning, I notice that the overall brightness on the MSI monitor is dimmed--except for a single window (it's usually Microsoft Teams, but not always). It's incredibly annoying. I've checked every display setting that I can think of but I'm not aware of anything that would configure this behavior (one window brighter than all the others). My employer's IT support suggested updating the montior firmware, which have done but it hasn't made a difference.

The only workaround that I know of is to open the Nvida Control Panel got to "Change Resolution" and switch between the options Use default color settings and Use NVIDA color setting. It doesn't matter which I switch to; just switching will reset the brightness

Can you make a photo to show about this issue?
What FW the monitor is using?

Does this issue happens after wake up from sleep?

Ok, so here's a screenshot. It's definitely computer independent: this is from the machine connected via the USB-C input. It's a little hard to see, but the Team window on the right is "bright", but the browser and Outlook email is "dimmed".

When I have switched back to the machine connected via DisplayPort I don't see the same bright/dimmed effect.
