Reposting from https://discourse.mozilla.org/t/firefox-upgrade-from-115-116-results-in-broken-screen-capture/121964 Howdy folks! I am on Arch Linux and recently upgraded Firefox from 115 to 116 and this broke WebRTC screen capture. Whenever I try to share my screen in Microsoft teams and Google Meet, the participants only see a black screen with a cursor. I am able to reproduce the issue on this test page. I had to downgrade to 115 in order to “fix” this critical feature. Before that it was broken in 114 and I had to use Chromium for presentations. I no longer want to touch Chrome with a 100 ft pole since they are trying to introduce Web Environment Integrity. The only bug I have been able to find is from three years ago: https://bugzilla.mozilla.org/show_bug.cgi?id=1640771 I don’t want to add a “me too” comment, but was wondering how to show/give my support to get this issue fixed? It is crippling to my work workflow, and I don’t want to be on 115 forever. I am an engineer so I can provide advanced support to a Firefox dev, just not development as firefox is gargantuan beast of a code base. Any guidance or pointers would be appreciated, Thanks!
