darfeikus <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #9 from darfeikus <[email protected]> --- I can confirm this bug also affects PlasmaShell itself on Arch Linux. In my case, right-clicking the Plasma desktop reliably triggers the failure and causes the desktop, panels, and widgets to disappear briefly while PlasmaShell restarts. Plasma Workspace: 6.7.4-3 KWin: 6.7.4-7 KWindowSystem: 6.29.0-1 plasma-integration: 6.7.4-5 Qt/Qt Wayland: 6.11.2 Session: Wayland GPU: NVIDIA RTX 5090 NVIDIA driver: 610.57.04 The journal records the same sequence reported here: plasmashell: ext_background_effect_surface_v1: error 0: tried to set blur region on destroyed surface plasmashell: The Wayland connection experienced a fatal error: Protocol error systemd: plasma-plasmashell.service: Main process exited, code=exited, status=255/EXCEPTION systemd: plasma-plasmashell.service: Scheduled restart job KWin remains running, and there are no corresponding NVIDIA Xids, DRM errors, GPU resets, OOM events, or other GPU faults. Some occurrences also produce a coredump from the desktop.so KIO worker. This happens after PlasmaShell has already been disconnected, with the stack ending during process teardown around dlclose() and libGLX.so . It therefore appears to be a secondary teardown failure, as described in comment 7, rather than the cause. The exact tried to set blur region on destroyed surface error appears seven times in my retained journal: 2026-08-28 16:36:55 2026-08-28 16:41:08 2026-08-28 17:03:33 2026-08-28 17:17:42 2026-08-29 12:11:48 2026-08-29 18:32:33 2026-09-08 15:54:07 The first six occurrences predate my August 29 upgrades to Plasma 6.7.4, Frameworks 6.29, and Qt 6.11.2. The likely introduction point on this system was the July 25 upgrade from Plasma 6.6.5 to 6.7.3, together with KWindowSystem 6.27 to 6.28. This provides another PlasmaShell reproduction case involving a short-lived blurred popup. The desktop context menu appears to leave or reuse an ext_background_effect_surface_v1 object after its associated Wayland surface has been destroyed. -- You are receiving this mail because: You are watching all bug changes.
