Wobble causing shadows, glow and window artifacts on moving large windows

[ImFenyx]

Hyprland version

Hyprland 0.56.0 built from branch main at commit 88c6386 clean (chore: replace string concatenation with std::format ( 15652)).

Is this a regression?

No response

What's the bug?

When wobble is enabled, windows show intermittent rendering artifacts on the edges:

• Strange blur / overflow of the shadow (and glow if enabled)
• The artifact “bleeds” outside the apparent window/shadow bounds
• Happens on large floating windows (very noticeable)
• Also happens on monocle, but almost imperceptible and only on some frames

Disabling wobble removed this.
It was happening on shadows on old hyprland non-git versions, but disabling shadows fixed it, now apparently the shadows are fixed (idk if it was 54 or 55)

Reproduction steps

1. Enable wobble (this is my look.lua config):

hl.config({
	general = {
		gaps_in = 4,
		gaps_out = 16,
		border_size = 2,

		col = {
			active_border = { colors = { "rgba(cba6f7aa)", "rgba(cba6f755)" }, angle = 45 },
			inactive_border = "rgba(59595955)",
		},
	},

	decoration = {
		rounding = 10,
		rounding_power = 3,

		active_opacity = 1.0,
		inactive_opacity = 1.0,
		fullscreen_opacity = 1.0,
		dim_inactive = false,
		dim_special = 0.3,

		blur = {
			enabled = true,
			size = 2,
			passes = 4,
			xray = true,
			noise = 0.07,
			contrast = 2.0,
			brightness = 1.0,
			vibrancy_darkness = 0.95,
			special = true,
			popups = false,
		},

		shadow = {
			enabled = true,
			range = 16,
			render_power = 4,
			sharp = false,
			color = 0xaa11111b,
			color_inactive = 0xaa11111b,
        },

        wobble = {
            enabled = true,
        },

        glow = {
            enabled = true,
            color = 0x55cba6f7,
            range = 24
        },

        motion_blur = {
            enabled = true,     
        },
	},
})

2. Open a floating window and resize it larger than a normal monocle / almost full monitor size / larger than monitor size or just use monocle and look carefully at the edges while moving/resizing
3. Observe the intermittent blur/overflow on the shadow edges (only some frames on monocle and continuous on floating but ends when wobble movement blur (not motion blur) ends)

May i ask which dotfiles are you using? i really love the waybar config and the animations! i have been struggling to get my animations setup again after there was a change recently to spring animations.

[ImFenyx]

it's my personal dotfiles, i didn't copied from anywhere, to make good animations use google ai studio for free (gemini 3.6 flash and high thinking mode) and mention hyprland wiki animations page + luaified config news, gemini still uses legacy .conf

Would you like to share your animations.lua file somewhere so i can have a look at it?
