Windows 10: weird lines appear across my monitor when an applications window crosses past the edge of...

Whenever I switch tabs via the taskbar, in that instant where the old tab is fading out and the desktop becomes visible they appear. Once I figured out exactly how it works I can replicate it 100% of the time. The colors that flash across the screen also exactly correspond to those that are on the border of the screen when it fades out. disabling the setting "Animate windows when minimizing and maximizing" under performance options seems to be the cause. when disabled the lines no longer seem to appear.I have recently reinstalled my graphics drivers completely, and I have checked that everythi

Cursor "cross" is transparent

Hi RR and thanks for your reply and suggestion.

Here's an update from my end:

This only happens on my laptop screen when it is plugged into a second monitor.

• If Excel is on the second monitor, then the cursor cross is white.
• If the laptop isn't plugged into the second monitor then the cursor cross is white.

I think the same happens on all Office applications - certainly PowerPoint as well.

From this ^^above, I doubt it is an Excel setting. Not really sure where to start looking for a fix. The issue is that it impedes the use of the application as you keep losing where the damn cursor is.

 

Weird lines showing up on some applications

I get these weird lines around hard edges in some apps, that don't make sense.

The applications this has happened on include Signal, Microsoft Teams, and Europa Universalis 4.
