All "glass" parts of SM and the title bar on frames in "extra settings" set background blur to semi trans. All my glass is transparent, no blur.
Open the skin in SkinStudio and change all the transparent parts to semi transparent, instead of blur, under the extra settings tab, save the skin, and you should have nice transparency everywhere it is meant to be.
I hope this helps those with blur issues on Windows 10.
NOTE: This may have an adverse effect on any skinner created animations, but it will also allow WinFX animations to work on the Start 10 start menu, Start menus with blur will ignore WindowFX animations. According to Neil.
