Add a window rule to render while unfocused

[vaxerski]

Adds a renderunfocused window rule.

Needs testing

fixes #2701

[ntnn]

Tried it on glxgears with windowrulev2 = renderunfocused, title:^(glxgears)$, the rule was recognized but the FPS still dropped after moving it to an inactive workspace.

Edit: Made a second test with this:

windowrulev2 = tag +unfocused, title:^(glxgears)$
windowrulev2 = renderunfocused, tag:unfocused

To ensure that glxgears was getting the renderunfocused flag and it did:

Window 5c71fc3f5090 -> glxgears:
        mapped: 1
        hidden: 0
        at: 3373,1023
        size: 300,300
        workspace: 4 (4)
        floating: 1
        pseudo: 0
        monitor: 1
        class:

        initialClass:

it should drop to ~15 thats the current set amount.

seems to be working for me

the point isnt to render at max fps all the time is it? The point is to avoid apps stalling

[ntnn]

Oh ok - then it works, it was about 15fps.

Do you think we could get a configuration option for that?

I see that it's a timeout in milliseconds here: https://github.com/hyprwm/Hyprland/pull/7582/files#diff-dbcd1ce1e0b916536f17c999473ad9e22c014646ddb2df15c45d726884a3481cR131

I think it'd be enough to make that value configurable.

[vaxerski]

prolly yea

Yeah not max fps all the time but some games (like Elden Ring as mentioned in the issue) are fps sensitive and being able to configure it would be great.

Works like a charm!

FWIW, I had Elden Ring in the background for about 15 minutes @ 6634117 with the hardcoded 15fps while switching back and forth between workspaces, and it didn't trigger the framerate detection. The ability to configure that value is very welcome though. Thanks!

great work! fixed!
