More settings/improvements when scaling is used

[Moltanicaa]

When scaling is active, the empty area is filled with the background of the map. It completely ignores the set dimming settings and does not allow you to make it completely black. This increases the amount of resources consumed.

This seems to be a duplicate of this #13687 thread, but I'm talking about something a little different. In this regard, there is a small wish - is it possible to make a frame around the playing field in order to visually see the boundaries of the playing field?

I'm not sure what the point of this discussion is. Is it:

1. You want to have more settings related to the fullscreen background (such as dimming, as you mentioned), and a border around the inner contents, or...
2. You're bringing up the performance concerns?

In regards to the performance concerns, it should be mostly irrelevant since it's 2x draw and should be covered by the front-to-back render pass. However I found two points of concern that prevent this:

1. Textured sprites no longer contribute to the FTB pass because we've disabled the code that determines if the texture is opaque: https://github.com/ppy/osu-framework/blob/d5b072fc890ffcfccc6812170307d69c0071fcc0/osu.Framework/Graphics/OpenGL/Textures/TextureGL.cs#L154-L179
2. BufferedContainer currently doesn't know whether its contents are fully opaque or not, and so also doesn't contribute to the FTB pass.

As far as I understand from your discussion, there is some misunderstanding regarding the request. I am writing specifically about displaying the border of the active game ZONE, not the playing field (which, by the way, works very poorly, since it does not even closely display the real borders of the field)
The game zone includes all game elements + the playing field. With 100% dimming of the entire screen (including the area behind the game ZONE) and active screen scaling, I have no way to see the actual boundaries of the game ZONE (NOT THE FIELD). When playing, it is very important to visually understand how big or small the playing area is at the moment.

Actually the idea of being able to reduce the dimming and add a blur behind the background (the one behind the game ZONE) is a good idea, especially if you let it be customizable. But it will consume more resources.

Since we are talking about the border of the playing field here, can I make a separate discussion of the problem of its current implementation? The edge of the field is in the center of the closest point to the edge where a note can be placed, which is why it is very common for a note/slider to be outside the edge of this field.

UPD. #13167

What you may need is a specific zone of objects placed on the edge
this is related to cs, is cs higher the object will more smaller. The actual playing field will also be smaller

It doesn't seem to be in the same direction as our discussion, maybe I need to open another discussion

@Moltanicaa please do not derail discussion with unrelated issues. open a separate discussion (although I'm pretty sure one covering the issue you mention will already exist at this point)

[cdwcgt]

Sure. Will wait for more opinions.

I've been thinking about this for the past few days. We might need a kind of poll?
I'm not sure because I personally want to initiate this kind of investigation but I don't have that much influence.
Then I thought about making the osu official account(or peppy's twitter?) but maybe it's not necessary to do so
But it feels unrealistic to wait here for other players to respond. So I'm at a loss right now

Much of it depends on ppy's team, But I really hope to get an accurate answer as soon as possible.
