Strange browser behavior

Computer is Windows 10 v1903 running both Malwarebytes Premium and ESET NOD32 Antivirus.

The behavior occurs with both the Edge browser and Chrome.

The behavior is that the browser window, whether it was set to full screen or not, very rapidly reduces somewhat in size then expands back to its previous size multiple times in succession over a period of several seconds. This behavior is intermittent, but frequent. The behavior occurs regardless of whether or not there is something actively in the browser window, e. g. typing while composing email in Gmail.  I've watched it happen while I've been remoted into the computer just passively watching both Chrome and Edge.

In addition to scans from Malwarebytes and NOD32, I've run online scans from from Norton and TrendMicro.

I have not a clue what might be cause this bizarre behavior that's making it very difficult to work on the computer, and would appreciate any suggestions.

Thanks
Mark

It's an HP Pavilion All-in-One - 27-a010 about 2 years old. Looking for this info reminded me to start the HP Support Assistant to check for updates...of which there were none.

Okay. So far my suspicion is bearing out.  Sounds like the touch screen is registering phantom touches which causes apps to behave just as you describe.

Clean the screen, look for defects (the touch layer separating from the other layers), or disable touch to see if that helps.

I've disabled the touch screen, so now just wait to see if that resolves the issue.

I turned the touch screen off and that solved the problem!

Thank you, thank you!!
