[nvidia] Can't log into cloud services because of compositing is enabled

[Ihor Romanyshyn]

Hi there!
Tomorrow I have installed the new 20.04 and found that I can't log into Google, Microsoft, and Flickr because that small window looks empty. But I can log into Facebook and Foursquare, which is very strange for me.
So I used Google to search for my problem's solution and found this: https://askubuntu.com/questions/1086983/google-account-in-online-accounts-is-blank-from-the-start-in-ubuntu-18-10
And it helped me to see that window, so I'm able to log-in. But it's a bug, I think. Also, I think it's related to my GPU's proprietary nvidia-driver-390 and I'm planning to check it with xserver-xorg-video-nouveau later. Also, my laptop has internal graphics, which also may cause this problem. I'm ready to provide any additional information, just ask.

What expected: to log-in to Google cloud account with settings window.
What happened: an empty window appears.
Workaround: run Control Center from Terminal, using 'WEBKIT_DISABLE_COMPOSITING_MODE=1 gnome-control-center' to temporarily disable compositing for it.

I'm changed graphics driver to OpenSource and it resolved this problem for me. So it's related to Nvidia proprietary driver.

Thank you for your bug report, could you add your 'journalctl -b 0' log after getting the issue? Does the documentation browser work or does it has the same issue (it also use webkitgtk)?

[Sebastien Bacher (seb128)]

the issue looks similar to bug #1876143

Thank you for your reply!

Which documentation browser did you mean? If you mean Evince it works ok. If you mean that quick help for new users then please tell me where to find it because I removed it from my sidebar and now I don't know where is it. :)

Here is some interesting part of 'journalctl -b 0' when i tried to log-in to Google and Microsoft:

The documentation browser is 'yelp'

Interestingly, yelp works normally on my machine. But I think this bug is duplicate, so I clicked "Yes, it affects me".
