The values from a "Dynamic Overall Damage" window are constantly updated out of combat, resulting in a values constantly changing between [value] and [value + 1].

From function classCustom.UpdateBar#L511:

As you can see, the value is getting rounded, resulting in the value constantly changing between 659 and 660.

Proposition

There is no need for a "Dynamic Overall Damage" window to be constantly updating the values out of combat.
Make it stop, when we are out of combat, reflecting the same output from "Damage Done Overall".

All displays, including Dynamic Overall Damage, have their display code run every update interval. Combat or not.

Ye I noticed, I can kinda fix it by making the "search code" of said script return nil when I'm out of combat. That way it doesnt wiggle between two values. Feels like a dirty hack tho... 😢
