Windows 10 Desktop Background Bounding Box Pixels Not Erasing Correctly

When I stretch a bounding box on my desktop background (left click and drag into a moving rectangle) some of the rectangle's edge pixels do not erase completely. This requires a background refresh to redraw the desktop background.

I have already removed the graphics card driver and installed the latest Windows 10 driver from the card manufacturer. I also ran the SFC / scannow utility which did not detect any problems. I am running an AMD Phenom 64-bit system with a Nvidia 9500 GT card.

This appears to be a Windows 10 bug.

I wondered has anyone else has seen this problem?

Is the wallpaper you set to be your desktop background still present at the location it was set to be your background?  If you delete the source wallpaper, in some cases that can cause oddities in redraw.

The background can be a solid color or picture. It happens on the desktop background immaterial if it is solid or a picture. There is no missing source picture.

I notice that sometimes there is no problem. When I restart the computer, eventually this problem resurfaces.

When a selection box is drawn and stretched and then released, some of the pixels do not erase. This requires a background "refresh" to set the desktop background back to the correct pixel colors. This appears to be a Windows 10 bug.

Hm.  The notion that it starts happening after some time does tend to make me think it's not really a desktop problem so much as a possible resource exhaustion issue.  A screenshot might help here.

Hi,
I did not state correctly about the time issue. I meant to say that the problem disappears on some Windows sessions, and then when I restart the computer, the problem reappears. It is as if it is a problem that somehow depends upon the booted up state of the Windows system. It does not change with the amount of time the computer is on.

I am attaching a number of screen shots.

Here is my normal desktop:

Here are a number of shots with the weird pixels remaining from the selection bounding box:

Here is a screen shot with a high contrast theme:

Here is one of the other themes:

This last screenshot also has the bounding box itself included. See the other pixels that are "stuck" on.

Sometimes when Windows starts, the session goes on without this happening. If I restart the computer enough times, this problem reoccurs. The problem does not go away without restarting the computer. The weird pixels can be removed by refreshing the desktop background.

Thanks for your help.

As long as the wallpaper for the current background still exists at the location it was set to be the background from (read this as "sometimes moving or deleting the current wallpaper can cause strangeness), everything should be fine here.  I'm not aware of any relevant issues on the wallpaper/background side here.

Does using your system at a lower resolution help avoid this problem?  That's clearly not a solution, but might point out whether it's something going on with the graphics card driver.

The lower resolution modes have the same problem.

I wonder if anyone else has seen this problem?
