I'm also running into this.

@ernstp Thanks for reporting this 2nd occurrence. I'd ask to you about to environment. is it also a Ubuntu Jammy, same driver? Could you compare against the information detailed in my first comment if there is something that could narrow down the issue?.

[ernstp]

Yeah very similar setup. Ubuntu Jammy, amdgpu graphics, Gnome Shell wayland session, Cog wayland platform.

cog-0.18.1 or cog-git
libwpe-1.14.1
wpebackend-fdo-1.14.2
wpewebkit-2.42.2

gtk4 backend works well afaict.
