I'm using Ubuntu 22.04.2 on a machine with NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] (rev a1). This morning, as usual, I ran the Ubuntu Software Updater, which installed some changes. I didn't look very carefully at what: my bad, I did see it updated Thunderbird but that's fine.
Now I find that Chrome, Vivaldi and Opera are hopelessly failing to render pretty much any page and none of them will launch their settings interface usefully: all three just show a blank so I can't change anything in the browsers. Same in incognito mode in Chrome.
Every other piece of software I am using seems to be fine including Firefox. Running Chrome in my Windows 10 in a VirtualBox VM on the machine is also fine.
I conclude this is almost certainly some nasty corner case involving the rendering engines of these browsers (I think they all use the same one don't they?) and something that has changed in the Ubuntu video drivers. It's a pain as use all four browsers normally to keep different work on the web separate. Is anyone else seeing this or similar?
