Bug 265460 – [GTK] Crash in webkitWebViewBaseEnterAcceleratedCompositingMode with WEBKIT_DISABLE_COMPOSITING_MODE=1

• Component: WebKitGTK
• Status: NEW

[Jim Mason]

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.

Rebuilding with RelWithDebInfo, I get this:

FYI, this is still happening as of my latest build from main (276084@main).

This occurs only with WEBKIT_DISABLE_COMPOSITING_MODE=1

[Jim Mason]

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.
