Display error. Horizontal stripes

in flag

Stripes began to appear on the screen. I don't know why. It happens without any action. Ubuntu starts as soon as it boots up.

Try this one: https://askubuntu.com/questions/1185787/screen-redraw-issue-lenovo-yoga-s940-ubuntu-19-10-feels-laggish/1185841#1185841 This adds a boot parameter that disables a power saving feature of intel cards. If that does not help, you can undo.
