It appears 'pipe' is NULL in the Mesa source at: static void end_query(struct gl_context *ctx, struct gl_query_object *q) { struct st_context *st = st_context(ctx); struct pipe_context *pipe = ctx->pipe; bool ret = false;
st_flush_bitmap_cache(st_context(ctx)); if ((q->Target == GL_TIMESTAMP || q->Target == GL_TIME_ELAPSED) && !q->pq) { q->pq = pipe->create_query(pipe, PIPE_QUERY_TIMESTAMP, 0); q->type = PIPE_QUERY_TIMESTAMP; } I can't reproduce the problem myself so I wonder are you using two GPUs? Do you have a monitor plugged into an Nvidia GPU? ** Bug watch added: gitlab.freedesktop.org/mesa/mesa/-/issues #9889 https://gitlab.freedesktop.org/mesa/mesa/-/issues/9889 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/2037497 Title: gnome-shell crashed with SIGSEGV at NULL from end_query() from cogl_gl_create_timestamp_query() from cogl_onscreen_egl_swap_buffers_with_damage() Status in Mesa: New Status in Mutter: Fix Released Status in mesa package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Status in mesa package in Fedora: Confirmed Bug description: crash after update wayland session is not accessible anymore ProblemType: Crash DistroRelease: Ubuntu 23.10 Package: gnome-shell 45.0-1ubuntu1 ProcVersionSignature: Ubuntu 6.5.0-5.5-generic 6.5.0 Uname: Linux 6.5.0-5-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.27.0-0ubuntu2 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Wed Sep 27 05:52:26 2023 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell InstallationDate: Installed on 2023-09-26 (0 days ago) InstallationMedia: Ubuntu 23.10 "Mantic Minotaur" - Beta amd64 (20230924) ProcCmdline: /usr/bin/gnome-shell ProcEnviron: LANG=fr_FR.UTF-8 PATH=(custom, no user) SHELL=/bin/bash XDG_RUNTIME_DIR=<set> RelatedPackageVersions: mutter-common 45.0-2ubuntu1 Signal: 11 SourcePackage: gnome-shell StacktraceTop: ??
