Reported 2023-11-28 08:37:54 PST
building from 2.42.2 (tarball) ENABLE_X11_TARGET=ON USE_GBM=OFF NVIDIA driver Normally, I experience flashing in websites like Google Maps or the Unity Tanks demo, so I always run with the environment variable WEBKIT_DISABLE_COMPOSITING_MODE=1 However, I have found a crash in the Bing ChatGPT page. The crash occurs only when WEBKIT_DISABLE_COMPOSITING_MODE=1; if I do *not* disable compositing, there is no crash. The stack trace is as follows. I have a doubt: the crash occurs in webkitWebViewBaseEnterAcceleratedCompositingMode. Should it be in this function when compositing is disabled? The issue does *not* appear to be a regression; I can reproduce this back to at least 2.40.5. Thread 2 received signal SIGSEGV, Segmentation fault.

I can consistently reproduce this crash on gnome gitlab: 1. disable ccompositing. Confirm in webkit://gpu 2. run with no GBM (? maybe) 3. run with X11 (? maybe) 4. Navigate to: https://gitlab.gnome.org/GNOME/epiphany/-/merge_requests/1489/diffs Backtrace is similar to before; commonality is that it is trying to enter accelerated compositing mode. One other thing: compositing has been permanently disabled for me from some weeks now, from about the time that GLX was removed or so. So I get this crash quite often in the wild, unfortunately. Backtrace and webkit://gpu output follow below. Thread 12 received signal SIGABRT, Aborted.
