Kwin blur effect - Respect rounded corners

This kwin effect is a fork of the default kwin blur effect, with minimal changes to solve the "plasma kornerbug". It works with all decorations, including aurorae one's, and take care of maximized windows, that are assumed to not have rounded corners.

Screenshot

Above left : Korner bug with the default blur effect

Above right : with the present blur effect

(Windows decoration : classikstyles by paulmcauly)

Usage

After installing the effect, go to Settings --> Workspace behavior --> Desktop Effects.

  • Disable the default blur effect ("Blur")
  • Enable "Blur - Respect rounded corners"
  • Tweak the settings of the effect to match your window decorations. Settings

Plasma version

I only tested the effect on plasma 5.23.3, I don't know if it work with older versions (But it should, the changes from the default blur effect are very minimal)

Installation

If you build a binary package, or make the effect available from the "kde get new stuff" service, let me know !

Unable to build on Neon User Edition

Your solution to the "corner bug" looked very promising. But I regret to say that it won't build in Neon User edition. I am not at all a programmer but perhaps the file I attached could give you useful information. Your screenshot looks fantastic! CMakeOutput.log

Bottom corners have a reverse korner bug

Even though I have set bottom corner radius to zero, there's a weird artifact in the bottom corners of blurred windows. plasmashell version 5.23.5 dolphin terminal A person from reddit has reported the same thing but the bug didn't disappear after multiple reboots. Also "no borders" option for maximized windows doesn't seem to effect the issue (I tried turning it off and reverse korners were still there).

Bottom corners clip squares while using LightlyShaders

While using Lightlyshaders (or ShapeCorners) here is a look at the bottom corner (extreme radius) image

And here is how top corners are handled at the same radius image

This causes the blur to clip into the window and shows transparent areas. I feel this is happening because we have to disable the window borders of the Decorations for LightlyShaders to take affect.

Is this dead?

The dev seems to be inactive and I can't compile this in Plasma5.25 due to an error image

I'd fix it if I knew coding or if someone was willing to guide me through it. Can someone take over?

Can't find KWaylandServer on Plasma 5.25

I'm trying to compile it on Arch Linux (Plasma 5.25) and I get this error...

CMake Error at src/CMakeLists.txt:13 (find_package):
  Could not find a package configuration file provided by "KWaylandServer"
  with any of the following names:

    KWaylandServerConfig.cmake
    kwaylandserver-config.cmake

  Add the installation prefix of "KWaylandServer" to CMAKE_PREFIX_PATH or set
  "KWaylandServer_DIR" to a directory containing one of the above files.  If
  "KWaylandServer" provides a separate development package or SDK, be sure it
  has been installed.

While (if I'm not mistaken) kwayland-server is merged into kwin now.
