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.

SOFTWARE VERSIONS
(available in About System)
