# kwin-effects-forceblur [](https://aur.archlinux.org/packages/kwin-effects-forceblur)
|
||
|
|
A fork of the KWin Blur effect for KDE Plasma 6 with the ability to blur any window on Wayland and X11.
|
||
|
|
|
||
|
|
Latest features are available on the ``develop`` branch.
|
||
|
|
|
||
|
|
|
||
|
|
<sup>Window opacity has been set to 85% for System Settings and Dolphin, Firefox uses a transparent theme | [NixOS configuration](https://github.com/taj-ny/nix-config)</sup>
|
||
|
|
|
||
|
|
# Features
|
||
|
|
- Wayland support
|
||
|
|
- Fake blur (optional, draws an already blurred image behind windows, which results in lower GPU usage)
|
||
|
|
- Rounded corners ([not perfect](https://github.com/taj-ny/kwin-effects-forceblur/issues/34), as it's currently just a pixel mask)
|
||
|
|
- Fix for [artifacts](https://github.com/taj-ny/kwin-effects-forceblur/pull/38) when using a transparent color scheme
|
||
|
|
- Ability to disable force blur for decorations, so that it won't interfere with ones that support blur, such as [Klassy](https://github.com/paulmcauley/klassy)
|

# Installation
|
||
|
|
## NixOS
|
||
|
|
``flake.nix``:
|
||
|
|
```nix
|
||
|
|
{
|
||
|
|
inputs = {
|
||
|
|
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
|
||
|
|
|
||
|
|
kwin-effects-forceblur = {
|
||
|
|
url = "github:taj-ny/kwin-effects-forceblur";
|
||
|
|
inputs.nixpkgs.follows = "nixpkgs";
|
||
|
|
};
|
||
|
|
};
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
```nix
|
||
|
|
{ inputs, pkgs, ... }:
|
||
|
|
|
||
|
|
{
|
||
|
|
environment.systemPackages = [
|
||
|
|
inputs.kwin-effects-forceblur.packages.${pkgs.system}.default
|
||
|
|
];
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Building from source
|
||
|
|
Dependencies:
|
||
|
|
- CMake

||
|
|
- Plasma 6
|
||
|
|
- Qt 6
|
||
|
|
- KF6
|
||
|
|
- KWin development packages
|
||
|
|
|
||
|
|
```sh
|
||
|
|
git clone https://github.com/taj-ny/kwin-effects-forceblur
|
||
|
|
cd kwin-effects-forceblur
|
||
|
|
mkdir build
|
||
|
|
cd build
|
||
|
|
cmake ../ -DCMAKE_INSTALL_PREFIX=/usr
|
||

# Usage
|
||
|
|
> [!NOTE]
|
||
|
|
> If the effect stops working after a system upgrade, you will need to rebuild it.
|
||
|
|
|
||
|
|
Since kwin-effects-forceblur is a fork, you need to disable the stock blur effect and any other blur effects you may be using. Using force blur together with another blur effect will result in blur being applied twice.
|
||
|
|
|
||
|
|
1. Install the plugin.
|
||
|
|
2. Open the *Desktop Effects* page in *System Settings*.
|
||
|
|
3. Disable any blur effects.
|
||
|
|
4. Enable the *Force Blur* effect.
|
||
|
|
|
||
|
|
For more detailed descriptions of some options, check out the [wiki page](https://github.com/taj-ny/kwin-effects-forceblur/wiki/Configuration).
|
||
|
|
|
||
|
|
### Window transparency
|
||
|
|
The window needs to be translucent in order for the blur to be visible. This can be done in multiple ways:
|
||
|
|
- Use a transparent theme for the program if it supports it
|
||
|
|
- Use a transparent color scheme, such as [Alpha](https://store.kde.org/p/1972214)
|
||
|
|
- Create a window rule that reduces the window opacity
|
||
|
|
|
||
|
|
### Obtaining window classes
|
||
|
|
The classes of windows to blur can be specified in the effect settings. You can obtain them in two ways:
|
||
|
|
- Run ``qdbus org.kde.KWin /KWin org.kde.KWin.queryWindowInfo`` and click on the window. You can use either *resourceClass* or *resourceName*.
|
||
|
|
- Right click on the titlebar, go to *More Options* and *Configure Special Window/Application Settings*. The class can be found at *Window class (application)*. If there is a space, for example *Navigator firefox*, you can use either *Navigator* or *firefox*.
|
||

# High cursor latency or stuttering on Wayland
|
||
|
|
This effect can be very resource-intensive if you have a lot of windows open. On Wayland, high GPU load may result in higher cursor latency or even stuttering. If that bothers you, set the following environment variable: ``KWIN_DRM_NO_AMS=1``. If that's not enough, try enabling or disabling the software cursor by also setting ``KWIN_FORCE_SW_CURSOR=0`` or ``KWIN_FORCE_SW_CURSOR=1``.
|
||
|
|
|
||
|
|
Intel GPUs use software cursor by default due to [this bug](https://gitlab.freedesktop.org/drm/intel/-/issues/9571), however it doesn't seem to affect all GPUs.
