`blur_new_optimizations=1` causes flashing

[JustSimplyKyle]

1. open an xwayland window(the example here being webcord)
2. have a eww bar open
3. turn off your internet
4. webcord started flashing https://github.com/hyprwm/Hyprland/commit/a163ca92377a56c196222a48c0a5676a7bb4ac3b this might be the commit that introduced it, haven't got time to thoroughly check tho

can't repro.

Is the window opaque?

Define flashing. What is flashing? webcord? the blurred background?

git bisect would be useful.

blurflash.webm

(i'll do the git bisect)

decoration {
    active_opacity=0.9
    inactive_opacity=0.87
    fullscreen_opacity=1
    multisample_edges=1
    rounding=15
    blur=1
    drop_shadow=true
    shadow_range=15
    blur_size=3 # minimum 1
    blur_passes=3 # minimum 1, more passes = more resource intensive.
    # Your blur "amount" is blur_size * blur_passes, but high blur_size (over around 5-ish) will produce artifacts.
    # if you want heavy blur, you need to up the blur_passes.
    # the more passes, the more you can up the blur_size without noticing artifacts.
    blur_new_optimizations=1
}

After doing a git bisect, I can indeed confirm that https://github.com/hyprwm/Hyprland/commit/a163ca92377a56c196222a48c0a5676a7bb4ac3b this is the commit that introduced the bug
