1.Turn off the monitor; if left unattended for an extended period, the Crystal-Dock (budgie-panel) will disappear.
2. High memory consumption during computer sleep mode or screen protection can easily cause memory leakage.

Crystal-Dock causes memory leaks. After prolonged use, the bottom panel will disappear and eventually consume all memory, leading to system crash.

Crystal-dock has nothing todo with budgie panel.

You can see the dialog process spinning close to 100% in that picture. You can kill that process.

Have you got the testing PPA installed from here ? The logout/shutdown/restart buttons on the graphical interface sometimes don't work(Ubuntu Budgie 26.04 wayland) - #8 by fossfreedom

PPA installed from here —> use git-core:


sudo apt update

I dont know what that PPA is but it isnt the testing PPA. You dont have that installed :frowning:

During a Wayland session, manually turning off and then turning on the monitor power causes the Crystal Dock and Budgie Panel to disappear—unlike automatic system sleep mode. This is a classic case where the Wayland synthesizer fails to properly handle physical display hot-plugging/wake-up events, resulting in failed UI component redrawing.

Analysis of the root causes of the problem:

  • Wayland’s “Output” Management Mechanism
    Unlike X11, which manages the screen globally, Wayland dynamically manages each output using synthesizers such as Mutter.When you physically turn off the display, the synthesizer receives an “output disconnected” signal; when you turn it back on, it attempts to re-register the output.However, third-party or desktop components like Crystal Dock and Budgie Panel often fail to properly detect enter/leave events from the output, causing them to remain “bound” to an inactive display port even after it’s awakened—making them essentially invisible.

  • The reason why the Budgie Panel has also disappeared

The Budgie Panel relies on the Layer Protocol of GNOME Shell.After a long display shutdown, if the synthesizer fails to promptly notify all panel instances to update their positions upon waking, the entire top bar or sidebar may disappear.This is typically related to the power management logic of the mutter.

  • Why does restarting solve the issue?

Rebooting will force all graphics components to reinitialize and re-register with the Wayland synthesizer, restoring everything to normal.But this is only a temporary solution.

This log is critical!It directly identifies the root cause: Qt applications (such as Double Commander) experience severe crashes in the Wayland environment, which is highly likely the primary culprit behind the instability of the entire desktop environment (including Budgie Panel and Crystal Dock).

:magnifying_glass_tilted_left: Analysis of Key Evidence
Fatal error: EAccessViolation (Memory access violation).
This means the program is attempting to read or write memory addresses it does not have permission to access.In Linux GUI programming, this typically occurs at the graphics rendering layer.
Crash location: libQt6Widgets.so.6 and libQt6Gui.so.6。
This is the graphical interface library for Qt 6.Double Commander, developed using Qt/Lazarus, crashed while attempting to render the interface or handle window events.

Environmental Conflict: Desktop Environment: Budgie (Wayland).
Key point: Although Qt 6’s support for Wayland has improved, compatibility issues persist on certain specific synthesizers (such as the Mutter/Wayland used by Budgie).Especially when the screen state changes (e.g., turning the display off and back on), Wayland sends a “reconfigure surface” signal. If the Qt application fails to handle this signal properly, it may cause memory boundary violations and lead to system crashes.

:hammer_and_wrench: Why does this cause the Dock and Panel to disappear?
Although Double Commander is just an app, its crash mechanism is quite “violent”:

Resource lockout: When a Qt application crashes under Wayland, it sometimes fails to properly release the graphics buffer or the Wayland protocol connection.

Synthesizer Chain Reaction: The underlying framework of Budgie is GNOME Shell/Mutter.When a heavyweight application crashes with an EAccessViolation, it can disrupt the synthesizer’s rendering cycle, preventing other components that rely on the same graphics stack (such as Crystal Dock and Panel) from refreshing their displays and causing them to “disappear visually.”

Ok. The SRU for the 100% budgie-polkit-dialog process has now completed its review and Canonical are happy and has released it. It will now appear in the 26.04 updates as mirrors pick up over the next day or so.

We can now concentrate on any additional issues in this area.

7

Crystal dock disappearing:

This is this issue

There is a proposed workaround posted on the 20th April for a systemd unit. That would need to be reworked to be more flexible.

Think thats the way to-go, introduce something like that … would need to be adjusted to only run if crystal dock is installed and only run if actually autostarted.

8

The panel in dock mode with the Icon Task applet already does the trick. Might as well stick to the KISS principle.
If only automatic masking worked the same way as it does in UB 24.04. :roll_eyes:

very good,I’m providing some crash information to help diagnose the issue.

%Y.%m.%d %H:%M:%S

  • Crash entry: g_type_check_instance_is_fundamentally_a → g_object_ref – A wild pointer or a destroyed GObject object is forcibly referenced.
  • At the call chain level: Wayland client event distribution → GDK3 Wayland backend → GTK3 window signal triggering → Budgie ShowTime clock plugin
  • Trigger condition: Labwc (Wayland) turns off the display power (DPMS sleep mode)
  • Phenomenon chain: Budgie-panel and Crystal-Dock both crashed simultaneously, involving GTK3 Wayland client components.

Core Bug Cause: When Labwc sends a DPMS display offline event:

  • GDK Wayland destroys the corresponding display/surface GDK object
  • The signal callback functions of the Budgie ShowTime plugin, CrystalDock, and Budgie Panel do not perform object existence validation.
  • When a dormant event triggers a callback, the control object has already been released; however, g_object_ref is still executed, directly causing an GObject assertion crash.
  • The Ubuntu 26.04 Budgie + Labwc combination features: a native Budgie window manager that supports the DPMS object lifecycle, and a Labwc compatibility layer lacking synchronization and destruction mechanisms
10

Interesting. Its the showtime raven widget that is crashing. Specifically crashing when calling a wayland specific routine.

This one is also failing; it might be affected as well.This one is also failing; it might be affected as well.

On a regular PC (not a laptop), turning off the monitor power and then turning it back on after 1–2 hours will cause the Budgie Panel and Crystal Dock to disappear.
