Bug#901604: xwayland: reliably crashes the system when opening certain pages in firefox
Package: xwayland
Version: 2:1.20.0-2
Severity: normal
Dear Maintainer,
when I open certain pages in firefox, the Xwayland process goes
to 100% CPU time, the firefox window becomes unresponsive, and
trying to switch to another window hangs the complete system.
example web pages:
https://gallery.technet.microsoft.com/scriptcenter/Reset-Windows-Update-Agent-d824badc
http://www.companyweb.be/gratisbtwopzoeken_recherchertvagratuit.asp
This happens even if I open the web pages in new tabs, without
displaying the tab. It could be related to the shortcut icon,
since wayland hangs before the icon is displayed in the tab bar.
This happens under the default gnome session, but not with gnome
on xorg, so I have an easy fallback solution.
Please don't hesitate to ask for more info or tests, I have no
idea how to debug such a crash, but I can follow instructions :-)
Thanks for your work,
