Description tromzy 2018-11-08 08:31:19 UTC 
SUMMARY
I have blur enabled, I would like to use this theme :
https://store.kde.org/p/1243914/

It is a transparent window theme using Qtcurve. Unfortunately, the blur is not applied in a Wayland session. Blur works fine on other elements of the desktop (plasma panels, Konsole background, etc.)

I also tested a Kvantum transparent window theme and the same problem occurs : no blur behind transparent windows.

STEPS TO REPRODUCE
1. On Wayland, use a transparent Qtcurve or Kvantum window theme like the one I provided above.
2. Enable blur in Kwin desktop effects
3. 

OBSERVED RESULT
No blur on transparent windows

EXPECTED RESULT
Blur should be applied like it is on X11.
