On Ubuntu Budgie 26.04 with Wayland, the sleep/wake budgie-panel disappears and the system freezes

Budgie Desktop
1

On Ubuntu Buggie 26.04 with Wayland, after turning off the display for 30 minutes and reopening it while entering a password, both the top and bottom desktop bars disappeared completely. Opening the terminal and typing “FIREFOX” followed by a web address caused the system to crash. Additionally,
running “gnome-shell quit–logout” failed to log out.

After entering sleep mode or waking from cover closure, the processes on the Budgie Panel (top bar) and Crystal Dock (bottom bar) crash and become unresponsive.
The labwc compositor encounters an abnormal redrawing logic error; opening an X11-compatible program (such as Firefox or WindTerm, which use Qt/XCB libraries) immediately causes a deadlock.

Segfault error in the budgie-panel section: The device crashes immediately after being awakened.
OOM: Memory is exhausted; the system automatically terminates the budgie-panel process.
The Budgie panel consumes nearly 40 GB of virtual memory and 22 GB of physical memory. When memory runs out, it crashes due to OOM (Out of Memory), causing the top bar to disappear completely. Reopening Firefox or WindTerm after full memory exhaustion leads to complete system freeze, and logging out produces no response.

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

The computer has been in use continuously without entering sleep mode, causing the bottom panel to disappear automatically.

What applets and raven applets are you using?

I suspect one of these is spinning out of control when the display turns off and using up memory. All applets run under the budgie-panel process and hence why you see all the memory being using under that.

I was referring to all the applets on budgie-desktop-settings - panel (top) and panel (bottom) plus the raven widgets in BDS - raven

There’s another strange issue: the Docker option at the bottom disappears after prolonged use. I don’t know how to restore it.

When the monitor is turned off and the computer remains unused for an extended period, Crystal-Dock and Budgie-Panel will disappear. Fix this bug promptly as it significantly impacts user experience.
