Hi,
I'm using a multimonitor setup (1 landscape and 1 portrait) and the taskbar from my secondary montiror (the portrait one) flashes for a second near the top of the screen on my primary if I do a specific thing. I usually have 2 apps open on my secondary monitor, the screen is essentially halved between them. When I pull the cursor over them, and the cursor changes to the 'change the size of this window arrow' that's when the taskbar flashes on the primary monitor. I recorded a video of the thing, I'll attach it here.
Any ideas what could be causing this? The flashes are quite distracting when moving the cursor between the applications.

Hi,
I've done the steps you requested. The timestamp of the event should be 20:39.

That's really strange, I can't say I've ever seen that before, and nothing weird is showing up in the log.
I wonder if it's a mix of Windows/.NET Framework/graphics driver causing it, can you make sure those are up to date and see if the issue persists?

I'm on Win11 24H2, no updates available in Windows update. For .NET, AFAIK those are also installed from Windows update.
I'm using the latest Nvidia drivers currently on an RTX 5080, the issue was also present on an RTX 3070 with older drivers and also an AMD 9070 XT with the latest AMD drivers.
