feat: force render

[busyoGG]

Allows the user to force a window to render even when it is offscreen or being captured by a screencast.

This behavior is controlled by the following window rule:

window-rule {
    // match rule
    force-render true    // not needed if the window is being cast
    force-render-fps 60 // if you need fps limit
}

For screencast it should work out of the box; but why would this be needed outside a screencast?

For screen recording, it already works out of the box without any configuration.

Sometimes I run turn-based games with an auto-battle feature on another workspace, and if rendering doesn’t happen, the battle logic can’t complete.

Iirc Yalter said that clients should expect this and handle it properly instead.

Hyprland also offers a similar feature.

I think providing a special solution to address this issue is also acceptable.

If you don’t use it, it’s equivalent to not running this logic.

Yeah. That's how it works on GNOME etc

KDE's equivalent would be the window rule
Block Compositing: Force No

I don’t think it does the same thing.I just tried it and it doesn't force render the game on another workspace.

Nevertheless, in some retro games where game/network logic is bound to its fps, it'd be nice to have this window rule.

Oh I really need it lol
I play Honkai Star Rail, it has auto-battle mode, that I can run the game in back ground, but the background window frame limit makes it run very slow, so I have to wait for long time until the battle be completed.
When I use Plasma, there are some ways to resolve it, but I don't know how to do this on Niri.
