Can any body make me clear why this code is showing GPU overdraw for one time? Instead of no overDraw?

[ephemient]

the activity itself may have a background (check the xml theme)

[Farhazul Mullick]

No full compose.

<resources>
    <style name="AppTheme" parent="android:Theme.Material.NoActionBar"/>
</resources>

Thanks!! I
tried android:Theme.Material.Light.NoActionBar in styles.xml
and background color of composable to Color.Transparent
and it reduced overdraw.

I think you do typically still want to have a theme as you need it for launch (unless i suppose you're using androidx.splash).

I think I also heard @romainguy say that overdraw in compose isn't really an issue.

[romainguy]

Yes on both counts

[romainguy]

Keep a window background/theme

[romainguy]

Don't worry too much about overdraw

[Farhazul Mullick]

But it can be considered as performance improvement doesn’t it have effects on compose?

[romainguy]

Nah, not really on today's GPUs

(also the rendering piepline can optimize this specific use case)
