Sony offers official statement on Xperia stripe display issues
It appears that Sony's flagship smartphones from last year have been plagued by weird display issues that no one managed to explain until now. The entire Xperia XZ1 lineup was experiencing these problems where sometimes stripes would pop up on the display.
Unfortunately, the same issue seems to affect some Xperia XZ2 units as well, though the number of people who experience the stripe display issue is currently unknown. Many haven't reported the issue since the stripes disappear from the display if you tap on the screen several times.
The folks over at Tweakers received an official statement from Sony that confirms the issue, but the Japanese company says this isn't a manufacturing defect but the result of … static electricity.

Sony Mobile is committed to providing the highest standard of product quality and customer service for all of our products. Due to the characteristic of the display, you may see stripe patterns as a result of electrostatic in some models. This is not a functional defect and usually the stripe patterns fade away as the electrostatic disappears.
Basically, the issue appears due to warm and humid places, so if it will not affect all Xperia XZ1 and XZ2 units. If you live in a cold and dry place, chances are that your phone won't be affected by static electricity.
