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.
