Cell color in a table ignition 8

Hi All!
I have a table where the backgroung changes if the value greater than 0 to green. Works great. In 7.9.
In 8.03 it first only paints a thin line to green, then when I click on another cell in the table it will repaint the whole cell as green.

Ver 7.9 image

Is this the same project upgraded to 8?

how are you painting them exactly?

Yes, upgraded from 7.9.
I don’t paint, I using Table customizer, P-bar background.

Looks like the cell is in edit mode in v8.

Noop.
