I'm using Firefox 115.0.3 on Windows 10 and a few updates ago Firefox started full screening, the text gets less sharp, hangs for about 2 to 5 seconds and then closes. Sometimes after it hangs it will allow me to scroll again but most of the times it closes itself automatically like it crashed but doesn't give me a prompt or ask me to send a report. I've turned off hardware acceleration but it still does it even with it off. It also only happens in Firefox and is more frequent when scrolling sites like Facebook.
