I have figured out how to solve this problem. Nowhere on the internet have I come across the solution. It may be out there, but it is hard to find. Here is how to solve the problem permanently: 1. Go to Control Panel > Intel (R) Graphics and Media. 2. Select /Click "Advanced". 3. Select/Click "Power" on the left. 4. On the Power drop down at the top, select "On Battery" to display the settings while on battery power. 5. Under the "Power Conversion Features", uncheck the "Display Refresh Rate Switching". 6. Click Apply and OK. 7. Problem is solved - Squiggly line artifacts gone. Some additional information that I discovered while troubleshooting: 1. The problem ONLY occurred while on battery power. 2. The squiggly line artifacts would almost always appear after 1 to 2 minutes of inactivity followed by a tap or double tap on the mouse pad. 3. The squiggly line artifacts would disappear in about 30 seconds. 4. The squiggly line artifacts could be "locked in" if you opened notepad, trigger them to appear, and then started typing in notepad after they appeared. The squiggly line arrtifacts would remain until about 5 seconds after you stopped typing. 5. Never did the squiggly line artifacts prevent anything from being clicked. 6. The problem could not be triggered if an external monitor was connected (presumably because the monitor being plugged in changed the resolution and Refresh Rate Switching). I have spent literally months trying to figure out how to trigger this problem and then how to solve it. I had already zeroed in on something with the graphics chip. With the help of a coworker, we discovered how to fix the problem. I hope this helps someone.
