I haven't touch to my SCT/SCTD addon, but something has changed ...
Now, as you can see on this screen, there is an icon with my spells, and I find it ugly. I didn't find the option to disable it.
When I do a critical strike, my screen become blue, and when I am hit, it become orange ...
And eventually I have now a big "Backlash" in the center of my screen...
The blue and orange screen color isn't from sct, you must have another mod doing that. Icons were added to sct a while ago - you must have just picked them up in your updates today. There is an option, but I forget where in the menu it is. But there is one.
Backlash I think is from sct - check out the options about notifications.
