This page tracks the Wayland showstoppers throughout the stack. Showstoppers are major bugs, crashes, or missing features affecting the Wayland session but not the X11 session. This is part of KDE's [[Goals/Wayland|Wayland goal]].
This page tracks the "Errata/Known issues" that are specific to the the Plasma Wayland session: significant quality-of-life annoyances, significant problems with workarounds, etc. This is part of KDE's [[Goals/Wayland|Wayland goal]].


It is the Wayland-specific companion to [[Plasma/X11 Known Significant Issues]].


== Clipboard management ==
* Plasma fails to paste text copied from XWayland apps: https://bugs.kde.org/show_bug.cgi?id=424754
* Text copied from a GTK app makes it into Klipper, but cannot be pasted after the GTK app quits: https://bugs.kde.org/show_bug.cgi?id=424649
* Can't copy text from notifications: https://bugs.kde.org/show_bug.cgi?id=434675 (very annoying for text messages with a long code you need to enter into a website for 2-factor authentication purposes)


== Login/Session management ==
== KWin/compositing/window management ==
* Session restoring does not include Wayland native windows: https://bugs.kde.org/show_bug.cgi?id=436318. Our sessions management recover engine is based on the [https://www.x.org/releases/X11R7.7/doc/libSM/xsmp.html X Session Management Protocol] and there is apparently currently no generic concept to do it on Wayland. But on Qt it's plugin-able and GNOME has —according to [https://wiki.gnome.org/Projects/SessionManagement/GnomeSession their wiki]— an own implementation for some time.
* Worse performance on external monitor connected to NVIDIA GPU when default GPU is Intel: https://bugs.kde.org/show_bug.cgi?id=452219
* Native Wayland windows cannot save and restore their window positions; KWin would need to do it: https://bugs.kde.org/show_bug.cgi?id=15329
* "Spare Layouts" feature not implemented: https://bugs.kde.org/show_bug.cgi?id=455431
* Using key combination shortcuts to type phrases into windows is not yet implemented: https://bugs.kde.org/show_bug.cgi?id=478219


== KWin/compositing/window management ==
== Accessibility ==
* When the compositor crashes, all apps die too: https://bugs.kde.org/show_bug.cgi?id=437709
* Can't move pointer with numpad keys: https://bugs.kde.org/show_bug.cgi?id=478620
* Window activation / launch feedback: https://invent.kde.org/plasma/kwin/-/issues/39
* Slow Keys feature doesn't work: https://bugs.kde.org/show_bug.cgi?id=490826
** Windows don't get brought forward when activated by another app: https://bugs.kde.org/show_bug.cgi?id=424795
* Only Maliit is supported, which is not a proper accessibility-oriented virtual keyboard (e.g. no modifier keys or arrow keys)
** No feedback on the Task Manager when an app is launched: https://bugs.kde.org/show_bug.cgi?id=402903
 
** No feedback on the cursor when an app is launched: https://bugs.kde.org/show_bug.cgi?id=405624
== Graphics Tablet Support ==
* Secondary screen doesn't come back on after disconnecting and reconnecting: https://bugs.kde.org/show_bug.cgi?id=434683
* Can't switch between absolute and relative modes for the graphic tablet. [https://bugs.kde.org/show_bug.cgi?id=477898 Bug report] and Pending Merge Requests [https://invent.kde.org/plasma/kwin/-/merge_requests/4852 1] and [https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/1963 2].
* KWin crashes when monitor goes into standby: https://bugs.kde.org/show_bug.cgi?id=420160
* Can't create multiple profiles for tablet configurations so artists can choose different profiles (e.g. different shortcuts and pen pressure) for different workflows like inking a comic or doing vector art: https://bugs.kde.org/show_bug.cgi?id=477671
* Very blurry fractional scaling for native Wayland windows due to using a downsampled 2x or 3x pixmap: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/34
* Can't map a portion of the tablet area to the screen. Some people have large tablet and sometime they want to map a portion of the tablet to the monitor: https://bugs.kde.org/show_bug.cgi?id=457703.
* Changes made to cursor theme/size do not take effect in Qt and XWayland software until the session is restarted (takes effect immediately in GTK software though): https://bugs.kde.org/show_bug.cgi?id=420859
* The UI for mapping tablet area and its buttons has a few issues compared to the UI in the X11 KCM: https://bugs.kde.org/show_bug.cgi?id=477750
* Desktop Grid effect is missing wallpapers: https://bugs.kde.org/show_bug.cgi?id=433071
* Graphic tablets may have a touch strip or ring, but in the Wayland KCM, you can't assign shortcuts to touch rings. Bug report: https://bugs.kde.org/show_bug.cgi?id=477752
* Context menus mis-positioned in multi-screen setups: https://bugreports.qt.io/browse/QTBUG-85297
* Some tablets allow users to switch between touch ring modes. For example, you can click a button and change the mode from one set of shortcuts like scrolling to another set of shortcuts, like changing hue or zooming in and out. This is not possible on Plasma Wayland: https://bugs.kde.org/show_bug.cgi?id=477787
* Windows that were closed when maximized will open in the maximized position, but not the maximized state: https://bugs.kde.org/show_bug.cgi?id=437089

=== Waiting on new Wayland protocol ===
* No session restore for native Wayland windows: https://bugs.kde.org/show_bug.cgi?id=436318 / https://invent.kde.org/plasma/kwin/-/issues/113. Our session management recovery engine is based on the [https://www.x.org/releases/X11R7.7/doc/libSM/xsmp.html X Session Management Protocol] and there is apparently currently no generic concept to do it on Wayland. But on Qt it's plugin-able and [https://wiki.gnome.org/Projects/SessionManagement/GnomeSession GNOME has had their own implementation] for some time. Possible workaround: Use Hibernation (Suspend To Disk) instead.
* Picture-in-Picture windows from web browsers get a Task Manager icon and do not stay on top: https://bugs.kde.org/show_bug.cgi?id=463288; requires https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/132 and adoption in apps using PiP windows (like web browsers)
* Calibration/Profiling tools like DisplayCAL and argyllcms are used with [https://en.wikipedia.org/wiki/Tristimulus_colorimeter colorimeters] to ensure monitors are displaying color accurately. A portal (which has not been proposed yet) is required for these tools to be able to calibrate the monitor on Wayland and hand the ICC profile over to the compositor as discussed [https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14#note_2125072 here]. Relevant DisplayCAL issue here: https://github.com/eoyilmaz/displaycal-py3/issues/133
* Global Menu is not supported for non-Qt apps: https://bugs.kde.org/show_bug.cgi?id=424485. Needed wayland protocol: see https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/52


== Plasma ==
=== Not yet started ===
* Context menus close immediately when the tooltip for thing that you right-clicked on closes itself: https://bugs.kde.org/show_bug.cgi?id=417939 / https://codereview.qt-project.org/c/qt/qtwayland/+/347783
* With screen scaling, cursor size is incorrect when hovering over native Wayland apps written with the GTK toolkit due to its lack of support for the cursor-shape-v1 protocol: https://bugs.kde.org/show_bug.cgi?id=451158. See also https://bugs.kde.org/show_bug.cgi?id=459161 for general cursor size issues.
* Panel disappears when connecting an external screen: https://bugs.kde.org/show_bug.cgi?id=438114
* Task Manager thumbnails sometimes don't work: https://bugs.kde.org/show_bug.cgi?id=427826
* Task Manager thumbnails sometimes show hue-rotated colors for XWayland windows: https://bugs.kde.org/show_bug.cgi?id=437744
* Saving and restoring activities does not work
* Activity switcher doesn't show up: https://bugs.kde.org/show_bug.cgi?id=437485
* KRunner doesn't render search results when using the proprietary Nvidia driver: https://bugs.kde.org/show_bug.cgi?id=432062


== System Settings ==
=== Work in progress ===
- Mouse settings don't work: https://bugs.kde.org/show_bug.cgi?id=438266
* When the compositor crashes or restarts, non-Qt apps are killed — Qt apps do stay alive, and work is ongoing to make other apps survive as well; see see https://invent.kde.org/plasma/kwin/-/wikis/Restarting


== Drag and Drop issues ==
=== Fixed in an upcoming version ===
* Can't drag-and-drop between Wayland and Xwayland apps: https://bugs.kde.org/show_bug.cgi?id=437406
* Can't fine tune pressure curve of the tablet. Various people draw with varying pressure; some people draw with heavy hand some use light touch. Configuring pressure curve helps artists to get better lines. [https://bugs.kde.org/show_bug.cgi?id=457705 Bug report] and [https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/1972 Merge Request]. - Implemented in Plasma 6.3.0
* Can't abort drag-and-drop with the Esc key while dropped file is over Plasma panel or desktop: https://bugs.kde.org/show_bug.cgi?id=405267
* Graphics programs that require color accuracy in professional settings such as Krita, GIMP, Scribus, Darktable, Blender, DaVinci Resolve, etc. cannot guarantee accuracy, especially when moving between color spaces like sRGB and CMYK (from digital to print) or Rec. 709 (broadcast TV) until the Color Management and HDR protocol is merged and compositors like KWin implement support for it: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14 - Implemented in Plasma 6.3.0 with KWin including support for the draft protocol. Apps can start implementing support too since the protocol is unlikely to change, and all that's left to get it completed is some XDG bureaucracy.
* When using a Chromium-based browser in native Wayland mode, dragging an image to the desktop creates a sticky note out of it: https://bugs.kde.org/show_bug.cgi?id=449645 / https://codereview.qt-project.org/c/qt/qtwayland/+/518017 (Fixed in Qt 6.6) + https://codereview.qt-project.org/c/qt/qtwayland/+/518018 (Fixed in Qt 6.8.2)
* QtQuick windows exhibit jittery resizing: https://bugs.kde.org/show_bug.cgi?id=477900 - https://codereview.qt-project.org/c/qt/qtwayland/+/591892 - Fixed in Qt 6.9.0
