Known issues in the Plasma 5.6 release.
Freezes Using Qt 5.6
When using Qt 5.6 Plasma loads itself incompletely and with long delays. Deadlocks occur in kded5. A potential patch fix is available but it is unclear how successful this is https://codereview.qt-project.org/#/c/151459/
Intel GPUs
We have received many reports on problems with running Plasma on hardware with graphic cards provided by Intel. We are sorry for the inconvenience and are sorry that we are not able to provide a product which is on par on all systems. Our aim is it to have our software run well on all hardware, but we cannot prevent errors in the underlying stack. Our software was hit by surprise by the issues which are from our view regressions in the underlying driver stack as previous versions worked fine. We would have liked to provide workarounds for these issues which can only be fixed by Intel. Unfortunately we were not able to find a satisfying solution. Given that we present here a list of known workaround which can be tried by affected users.
We encourage our users who experience problems to come to forum.kde.org so that we can help with our knowledge and to help us gather more information to provide better workarounds.
Random application crashes
This issue is caused by a (driver bug). A reported workaround is to change AccelMethod to UXA in the xorg configuration and restarting the system. Please refer to documentation provided by your distribution on how to change this.
Heavy rendering artifacts
Users told us that enabling DRI3 in xorg configuration can circumvent this problem. An alternative can be to use the new OpenGL ES backend in KWin which also seems to circumvent the problem or disable compositing completely.
KWin Wayland
- Integration features in Plasma still missing or incomplete (e.g. Pager applet, task manager)
- No support for xdg_shell which means GTK+ applications cannot be started on Wayland
- No Copy/Paste from X11 to Wayland windows and vice versa
- No support for animated mouse cursors Qt Bug 48181
- XWayland doesn't remove outputs Freedesktop Bug 92914
- XWayland older than 1.18 lacks features, no touch, no updates on screen hot plug
- Several effects break multi-screen rendering
- No focus stealing prevention for Wayland windows
- No window rules support for Wayland windows
- Screen configuration only partially implemented
Tech Previews
- Plasma Media Center is in tech preview and misses features compared to Plasma Media Center 1
- Breeze Plymouth Theme is in tech preview
- Breeze Grub Theme is in tech preview
Missing features
- KWin does not provide window tabs
- Tooltips on window decoration buttons
Configuration changes
Environment variables and shutdown scripts are now sourced from ~/.config/plasma-workspace/env and ~/.config/plasma-workspace/shutdown, respectively. Existing scripts from Plasma 4 should be moved there.
