This page lists a few ideas of simple tasks to be implemented in KWin. If you want to work on one, please check with the KWin team whether anybody is working on it already. If you need help on your task you can always contact the KWin team.
Tiling as KWin Script
KWin provides window tiling which is hardly maintained and unknown to the core KWin team. The idea behind this task is to reimplement the tiling functionality as a KWin Script. This has several advantages: tiling gets properly decoupled from KWin core reducing the maintenance costs for the core team. It would also proof that KWin Scripts are powerful enough to implement a complete new window management concept.
Use KWin::Options in KCMs
Since 4.9 the internal KWin::Options provide the default options as static member functions. In KWin's configuration modules the default values are still hard coded. It would make sense to use the static functions to set the default values.
Shader Support for AnimationEffect
The AnimationEffect provides easy ways to define animations for windows. This could be extended to allow uploading a vertex and/or fragment shader which is used when rendering a window. The AnimationEffect would in that case animate a uniform value of the shader.
QIcon for Window Icons
Currently KWin stores the window icons in different sizes as dedicated pixmaps. This could be changed to using just one QIcon with all provided sizes.
Port WindowPaintData to use QGraphicsTransform
The WindowPaintData allows effects to transform windows by setting a translation value, a scaling value and a rotation. This is also provided by the QGraphicsTransform and it's inheriting classes, which did not yet exist when the Effects Framework had been implemented. Using QGraphicsTransform makes it easier to apply the transformation in the compositor and to integrate better with QML based window thumbnails.
OpenGL 3 Support
Since Mesa 8.0 the free drivers support OpenGL 3. This would allow to initialize an OpenGL 3 rendering context if available.
Geometry Shader Support
After OpenGL 3 Support has been added to KWin the Shader Manager should be extended to support Geometry Shaders.
Use Geometry Shaders for Wobbly Windows Effect
After Geometry Shader Support has been added to KWin it should be possible to use a Geometry Shader to calculate the Geometry for Wobbly Windows Effect.
Use Geometry Shaders for Magic Lamp Effect
After Geometry Shader Support has been added to KWin it should be possible to use a Geometry Shader to calculate the Geometry for Magic Lamp Effect.
Dedicated Configuration Module for Present Windows/Desktop Grid
One of the main window management UIs of the KDE Plasma Workspaces are Present Windows and Desktop Grid. Unfortunately the user has to know about it and the configuration interface is very hidden. In this small project a dedicated configuration module should be written to configure Present Windows and Desktop Grid.
Better Default Options
KWin could need improvments for the default options. For example there is a default of one desktop. This implies that if the user changes to more desktops we can expect that he wants to use it. So desktop grid should be enabled by default.
