There is what I can only assume to be a bug with Opera GX that has made me switch browsers entirely. Seemingly randomly, Youtube videos in my history and home page will begin playing audio in the background of the browser, with no tab as a source to close.
On my headset is a button that I can press to play/pause videos currently playing on my PC. So when this bug occurs I press once to pause the ghost audio, then another video's audio will begin playing immediately after. Only after I pause the second video with my headset does it stop, but the bug will continuously occur so long as Opera GX is open. I cannot seem to find any pattern at which this bug will occur, it will simply happen at some point if the browser if open. Not only that, but after the bug occurs when I check my Youtube history AND likes there is a chance that it will be filled with completely random videos from different languages. A fresh install of Opera GX does not resolve the issue.
This has made Opera GX absolutely unusable as someone who has used this as their default browser for two years now. I can only hope this gets resolved at some point.
