What causes the blur to not work during animations?

[JugadK]

Just wanna say this is an awesome patch, my only issue with it has been during animations and the overview effect the blur seems to disappear? I'm starting to look through mutter's code to see if I could fix it but I was wondering if you had looked into this before? all the gnome app blur extensions seem to have a similar problem so I was wondering if its some deeper problem with how gnome works

kwin disables all "advanced" effects (like blur, rounded corners etc.) when you drag the window while wobbly windows is active. My guess would be that the damage calculation is probably too expensive.

Afaik macos does it similar. Windows and Android dont keep it blurred either. During animations they transition and overlay a gradient instead of animating the blurred area.
