Windows 10: Desktop pixelation and lagging mousepad

My mouse keeps freezing for like 5 seconds every times a try to make a selection. How can i fix this? And my background photo is pixelated, why?

Windows 10 Upgrade- Laptop Keyboard/Mousepad Lag

Since upgrading to Windows 10 from Windows 7, there is a lag between using my laptop keyboard and mousepad. I have an HP laptop that I bought almost 4 years ago and didn't have this issue until after the upgrade. The mousepad becomes completely unresponsive
after using the keyboard. I have to wait a few seconds before being able to use it again. I've seen that others are having issues with their wireless/USB devices, but this issue is with the actual hardware.

 

Random lag spikes

Hi,

We would like to know more about your lag issue:

• What browser are you using when you experience a lag?
• Does the lag occur in a particular game?

In the meantime, we suggest you run the System Maintenance troubleshooter. Here are the steps:

• Press Windows Key + X.
• Click on Control Panel.
• Select Troubleshooting.
• On the left pane, click on View All.
• Click on System Maintenance to run the troubleshooter.

Looking forward to your response.

 

Desktop pixelated when extended

Good afternoon,

Thank you for the reply. I followed the recommended suggestion and calibrated the monitor, however it did not help the situation. I do not believe this is an issue with the monitor since the pixilation does not occur uniformly.

Applications are not pixelated unless I extend the size of the window to exceed 1920 pixels horizontally (each individual monitor has a native resolution of 1920x1080). As long as the application can fit entirely within a single window then it remains unpixelated.
I can even have applications spread across both monitors so long as the application window does not exceed 1920 pixels. Once the window size of any individual application becomes greater than 1920 pixels horizontally that entire application becomes pixelated
(other applications open remain unpixelated so long as they are less than 1920 px horizontal).

The taskbar (including the start menu, notification area, and applications pinned to the taskbar) is never pixelated, however icons on my desktop are pixelated regardless of where on the desktop they are located. My desktop wallpaper is also always pixelated
regardless of resolution of the image I use or the settings I use (fill, center, span, etc).

As I mentioned in my original post, this issue only presented itself after a Windows update I received a couple months ago. I have been using this same dual monitor setup on Windows 10 for over a year prior to the update without issue.

All signs point to it being a software issue resulting from the update. The issue is not critical, just very annoying. If anyone has any other ideas as to how to resolve this I would be very appreciative.
