The bugzilla product kwin has several Components. Here a short overview is peresented.


Component general for untriaged bugs or not fitting anywhere else.


Core components include everything that is part of KWin core.


Bugs directly in the core of KWin. E.g. stacking order related


Everything related to Alt+Tab except effects


Everything related to window tiling.


Everything related to KWin's JavaScript itnerfaces

Client Grouping

Everything related to client grouping aka window tabbing. This is the crashers in core, but not the implementation in decorations.



Everything related to Activities


Everything related to KWin's window specific rules handling

Multi Screen

Multi screen related bugs


As before everything to multi head (two+ X servers)


Bugs related to XRandR (modern). General multiscreen issues should be put into this component.


Anything to Xinerama/Twinview (legacy).


Compositing related bugs in the core (not effects).


General bugs either in the effects library or it's implementation in core and scene.


OpenGL related compositor bugs.


Xrender related compositor bugs.



Bugs in the decoration libraries (KDecoration and KCommonDecoration) plus bugs in the bridge.


Bugs in various decorations shipped with KWin (e.g. Plastik), but not Oxygen (has own component and product) and not Aurorae.


Bugs in the Aurorae Theme Engine



Bugs in any effects not matching into the more specialized components.


Bugs in any tabbox related effects (boxswitch, coverswitch, flipswitch).


Bugs in effects for window management (e.g. PresentWindows and desktop Grid).

Components Systemsettings

KWin is also responsible for some Components in product systemsettings:

  • kcm_desktop
  • kcm_kwincompositing
  • kcm_kwindecoration
  • kcm_kwinoptions

Handling priority

For the purpose of making handling of (not so small number of) KWin bugreports simpler, each bugreport should have a priority assigned, making it possible to sort the list of bugreports and see what bugreports should be handled first. For consistent setting of priorities, these rules should be followed:


There are 5 priorities, VHI (highest), HI, NOR, LO, VLO:

  • VHI - urgent, should be handled as soon as possible. Examples: Broken trunk, stable branch often crashing for many people, basic often-used feature not working properly, etc.
  • HI - important, should be ideally fixed for the next release (meaning minor release, i.e. x.y.0). Examples: A crash that may happen for many people but is not critical, a basic but non-critical feature not working properly, very good idea for a new feature, etc.
  • NOR - the default, no priority has been assigned yet (new bugreports get this priority and should get other priority assigned)
  • LO - not important enough to be in the next release, low priority for when somebody will feel like fixing it. Examples: Relatively rare crash, not-often-used feature not working, feature request without important benefits, etc.
  • VLO - minor issues, too specific or questionable (but still reasonable enough, complete nonsense or "nobody will ever do that" should be closed with WONTFIX).

A short simple way of explaining the priorities is "VHI ASAP, HI reasonably soon, LO somewhen, VLO who knows when".


It is important to note that these rules are just guidelines and do not need to be strictly followed when it makes sense (for example, a minor crash that should be however simple to fix can get HI in order to be checked before next release). Specifically, the examples given are just examples and the description of the priority should be used. The main purpose of these rules is to help with handling many bugreports, not to have rules for the sake of having rules. It is not a big problem if at the time of a KDE release there are tens of HI bugreports.

Wishes should use the same priorities like normal bugreports.
