Description Davis Davalos-DeLosh 2023-03-22 21:52:27 UTC

Description of problem:
Epiphany hangs momentarily and then crashes when visiting certain pages like Reddit, Gitlab, etc. Websites like Google never cause the crash.

This occurs only on the Wayland backend (it did not happen using GDK_BACKEND=x11 and XWayland, but maybe that is just affecting how HW acceleration works?), and I tested it with /org/gnome/epiphany/web/hardware-acceleration-policy set to "never" and "always" and only reproduced it when set to "always"

I was unable to reproduce the problem in the builtin help browser of GNOME Builder which appears to be linking to the same libwebgtk library.

Version-Release number of selected component (if applicable):
Epiphany 44.rc / epiphany-44~rc-3.fc38.x86_64
WebKitGTK 2.40.0 / webkitgtk6.0-2.40.0-2.fc38.x86_64
GStreamer 1.22.1 / gstreamer1-1.22.1-1.fc38.x86_64

How reproducible: Sometimes: it seems to take ~3 tries of trying to load the same website for it to crash.

Steps to Reproduce:
1. Open Epiphany
2. Visit a post on reddit/gitlab, etc.
3. Crash

Actual results:
Program hangs before rendering page, then crashes

Expected results:
No crash
