I should probably note that I am also using the non-touch non-4K version (13-inch 1080p) screen with a clean install of 19.04. The "flash" does not appear if the Ubuntu image provided by Dell (18.04) is installed and then upgraded to 19.04. However it does occurs when 19.04 is clean installed via the Ubuntu ISO downloaded from canonical. The flash is much more obvious/annoying when the display is in "Night Light" mode.
