Plasma/Wayland Known Significant Issues

This page tracks the Wayland showstoppers through out the stack

General issues

NVIDIA

The NVIDIA blob is not supported as it uses a custom EGL extension. It would require additional code just for NVIDIA. On the other hand many users are on NVIDIA. Further information: To EGL Stream or Not

QT_QPA_PLATFORM

QT_QPA_PLATFORM is set to wayland breaking any application which has Qt included (e.g. appimages, proprietary software) and doesn't have wayland QPA.

No remote support

We don't have an API yet for remote support. Even if we had things like TeamViewer would not work any more.

Input

No (wacom) Tablet support

KWin lacks integration the tablet support from libinput. Also KWayland lacks wrapping the API for it.

No XModmap

We lack a functionality like XModmap to remap keys.

DRM

Modes cannot be configured

It's not yet possible to switch modes.

Output cannot be rotated

It's not yet possible to rotate the screen.

Plasma

Virtual Desktops

We don't have an API yet for virtual desktops, so pager is not working

No window thumbnails

We don't have an API yet for window thumbnails.

No window move on empty area in breeze

Broke with switch to XdgShellV6. Needs new API added to Qt (native interface), KWayland and Breeze.

Qt

No animated cursors

See QTBUG-48181

Key repeat not working

See QTBUG-55615

Compose key not working =

See QTBUG-54792

No tablet support

QtWayland does not yet support the tablet API. So even if KWin had support Qt would not be able to use it.
