I was forced to get a touchscreen by dell to get 4k. I never touch it, have an external keyboard and mouse. When I clean it, it produces a lot of erroneous input.

Perhaps you should turn off the touchscreen so you don’t accidentally trigger it.

Interesting, happens rarely so never thought of it:

    xinput list
    xinput disable 11

I have an XPS 13 with a 4K touch screen. I view it as an anti-feature that I occasionally brush with weird unwanted effects.
