This package is now renamed to kwin-effects-better-blur-dx-git to be in line with the name change. If there's interest in keeping the old version anybody can feel free to do now.

Users that had kwin-effects-forceblur-git installed should migrate to this new name

Attention X11 users: This package now only provides the effect for Wayland. You should install kwin-effects-better-blur-dx-x11-git

I filed an issue about this and the author now replied, package should build again.

@ShaiAvr This is a git package so expect breakages. The error is not a direct packaging issue. It's something you should report upstream on GitHub instead of here. They configured CMake to treat warnings as errors (default that comes from them using KDECompilerSettings).

When I updated my system today, this package needed an update. However, it failed to build. The last portion of the compiler's log is:

@PatchMixolydic Updated, should be clear now

The postinstall message is slightly misleading — it claims that the Better Blur DX effect is not compatible with Wobbly Windows:

If you have the Wobbly Windows effect enabled you should also disable it because it is not compatible at the moment.

This may mislead users into thinking that Better Blur DX has issues with Wobbly Windows that the vanilla Blur does not (or worse, that it completely breaks with Wobbly Windows), but as far as I can tell, no such issues exist. With Wobbly Windows enabled, Better Blur DX works just as well as the vanilla Blur: the blur effect is removed when dragging a window, but quickly returns once the window stops wobbling. This is mildly annoying, but difficult to notice in daily usage, and doesn't really affect the usability of either effect (at least for me).
