User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:80.0) Gecko/20100101 Firefox/80.0

Steps to reproduce:

Closed laptop lid with a page open (happens largely with YouTube videos but has been shown to occur randomly across other websites too). Resume from sleep to find the issue.

This occured on Pop!_OS 20.04 LTS which uses GNOME 3.

Actual results:

Browser window was completely transparent except for frame and title bar.

Expected results:

Page should have displayed as before.

Thanks! This is known and basicially the one Nvidia bug. It occurs with the old and the new OpenGL compositor. You are still using the deprecated one. Please open about:config, set gfx.webrender.all to true and restart Firefox. (It implies gfx.webrender.enabled and layers.acceleration.force-enabled, therefore you don't need to enable these two prefs.)

Ah, thanks for letting me know! I have dual graphics on this laptop and it makes sense since it did start occurring since after I switched on the NVIDIA set.
