A custom blur texture for the UI?
In various places in the Sailfish UI there is blurring. The blurring can be seen when calling someone, as just one example. The avatar is then less sharp and a bit dimmed. But it's not just blurred. The blur has a pattern too. In some places in the UI that pattern is more clearly visible. Just have a look at the "glowballs" that are used for a number of functions. I think you understand what I mean by now. If you look closely at one of those glowballs there is a pattern as if the glow came through textured glass. If you move one of those glowballs by scrolling then you'll notice that the textured pattern doesn't move. ...and that the pattern of that texture is regular and quite small.
A long time ago I tried to modify that texture in Sailfish OS 1.0. I didn't succeed in doing so but I created the pattern for it and uploaded it to somewhere at TJC (I can't find it but it's here somewhere). A custom pattern for the blur texture would add a way to customize the UI that isn't available in any other mobile OS. So...
Yes it is possible to have a custom pattern for the blurring.
Yes larger patterns can be used.
How large can it be? The same size as the ambiance?
Does a larger texture make the UI slower?
I didn't find the uploaded texture after some searching. Obviously it is obsolete now, but...

/usr/share/themes/sailfish-default/meegotouch/icons/graphic-shader-texture.png
. The file is very small and I imagine this means it's not expensive to have it running and of course, it tiles the entire screen area.I copied the texture to my PC and inverted it, then sent it back to my phone, there is a change in the appearance but it is very, very subtle.
The original texture file is only 16 pixels by 16 pixels.
