Similarly # 1874986 for 1920x1080

App grid can't switch pages.
Similarly # 1874986, but for 1920x1080.
Standard Ubuntu 20.04 by updating standard 18.04.
Two monitors: 1920x1080 (main) and 19201200.
The error appeared immediately after the update (~06.2020).
Solution "" Settings - Apperance - Submenu Dock (Bottom) "" works, but it does not suit me.
Is it possible to calculate the error correction.
Thank you.
