Environment: - KDE Plasma: 6.7.3 - KWin: 6.7.3 - KDE Frameworks KWindowSystem: 6.28.0 - plasma-integration: 6.7.3 - Qt: 6.11.1 - Session: Wayland - GPU: AMD Radeon RX 9070 XT - Mesa: 26.1.5 - Blur effect: kwin-effects-glass-git r646.fabad92-1 - Stock Blur and Translucency effects disabled Immediately after enabling the Glass blur effect, Plasma Shell was disconnected and restarted twice within approximately one minute. First occurrence: 2026-07-28 22:47:41 kwin_wayland_wrapper: error in client communication (pid 1327) plasmashell: ext_background_effect_surface_v1#87: error 0: tried to set blur region on destroyed surface plasmashell: The Wayland connection experienced a fatal error: Protocol error plasma-plasmashell.service: Main process exited, status=255/EXCEPTION plasma-plasmashell.service: Scheduled restart job, restart counter is at 1 Second occurrence: 2026-07-28 22:48:36 kwin_wayland_wrapper: error in client communication (pid 2177) plasmashell: ext_background_effect_surface_v1#74: error 0: tried to set blur region on destroyed surface plasmashell: The Wayland connection experienced a fatal error: Protocol error plasma-plasmashell.service: Main process exited, status=255/EXCEPTION plasma-plasmashell.service: Scheduled restart job, restart counter is at 2 KWin remained running and there were no AMDGPU faults, GPU timeouts, ring resets, or driver errors at either timestamp. This confirms that the stale ext_background_effect_surface_v1 issue remains present with KWindowSystem 6.28.0 and can terminate Plasma Shell, causing all panels, docks, desktop widgets, and the desktop itself to disappear and restart. -- You are receiving this mail because: You are watching all bug changes.
